12 Keys to Spiritual Maturity:

Putting Sin to Death – #3

Colossians 3:5-11

Suppose a man to be a true believer, and yet finds in himself a powerful
indwelling sin, leading him captive to the law of it, consuming his heart with
trouble, perplexing his thoughts, weakening his soul as to duties of communion
with God, disquieting him as to peace, and perhaps defiling his conscience and
exposing him to hardening through the deceitfulness of sin, –what shall he
do? what shall he take and insist on for the mortification of this sin, lust,
distemper or corruption.

Thus wrote the puritan, John Owen, in the middle of the seventeenth century.
His audience? Fifteen year-old boys then away from home at Oxford University
(where Owen was Vice-Chancellor) and, so Owen thought, with hormones coming out
of their ears! The volume in which these words can now be found (Volume 6 of his
collected writings) has justly remained a classic treatment of sin, and I
vividly recall reading for the first time over twenty-five years ago. I have
found nothing else that quite faces down the evil of indwelling sin with as much
vigor as Owen does. Too many books and sermons (of the latter I include my own,
of course) only touch the surface of the problem, failing to become too specific
for a host of reasons. But, conquering sinful habits (and habits are what
they become) is a mark of spiritual maturity. There can be no growth without it.
Dilly-dally here and the result will be something so fragile, so insipid that
ruin is bound to be the eventual result.

We have already looked at the importance of a desire for spiritual
maturity. It starts there. If we have no desire to grow, we will not grow!
If the heart is wrong, everything else that proceeds from it will be wrong, as
Jesus told the Pharisees again and again. In addition, we have seen how
important it is to think properly and accurately as to what it means to
become a Christian and be a Christian. For this we have looked at something Paul
tells the Colossians in chapter three. There he insists that there are two
things about ourselves we need to know and reckon with, if we are Christians: we
died with Christ and have been raised with Christ. As a consequence, we are to
seek those things which are above where Christ sits at God’s right hand. We
are to live with our heads above the clouds beholding something of the
glory and majesty of Jesus. We are to know who we are and what is true of us.
This is the positive aspect of sanctification’s path that Paul would have us

But there is also a negative side. There is a power to negative thinking,
Norman Vincent Peal notwithstanding! Paul wants us to appreciate that unless we
know what NOT to do, there is no use in telling us what we should do! There’s
a power in negative thinking as much as there is positive thinking. The key word
here is mortification. Its an old word, long known and loved by
readers of the King James Version of the Bible, but one which needs to be
reintroduced into our vocabulary. It means putting sin to death. Every Christian
must be engaged in the duty (yes, it is a duty) of putting sin to death.
“Kill a sin, or a part of a sin every day” was Owen’s advice.
“Kill sin, or it will kill you,” he added, suggesting as he did so
something of the seriousness of the issue. What is it that Paul tells us here in
Colossians 3 that we need to do? Three things:

1. He exposes the reality of what we are
2. He identifies for us in detail what needs to be dealt with
3. Practical indications as to how we go about this

1. He exposes the reality of what we
There is a general point that needs to be made if
we are going to be serious about dealing with indwelling sin. We need to say,
“I need to face up to the reality of ongoing sin.” We have been
delivered from sin’s reign but not we have as yet not been freed from the
presence of sin. A constant struggle ensues within us as the flesh lusts wages
war) with the soul. There is a spiritual opposition that is war-like taking
place in the innermost part of our beings. There is a need, therefore, to look
sin (personal and particular sin) in the eye.

We rush on in reading these verses, don’t we. We note the “up close
and personal” way Paul lists two sets of five sins, and we find ourselves
asking what they mean. But we need to stop and reflect for a moment on the
appropriateness of all this talk about sin. J. C. Ryle’s justly famous volume,
Holiness, begins with a statement to this effect: “He would make
great strides in holiness must first consider the greatness of sin.” Ryle,
writing at the end of nineteenth century was merely reflecting what Anselm of
Canterbury had written in the early middle-ages. Attempting to answer the
question, Why did God become man (Cur Deus Homo), Anselm has a famous
line put to one character (aptly called Boso) which goes like this: Nondum
considerasti quantum ponderis sit peccatum
. Roughly translated that means,
“You have not yet considered the gravity of sin.” Boso’s inability
to see the necessity for the Lord Jesus Christ to become incarnate in order to
save His people lay in his reluctance to place sufficient emphasis upon our need
of salvation. Our problem is sin. It has been so since the Garden of Eden; and
it remains so to this day.

What Anselm, Owen, and Ryle are saying is that we need to allow our hearts to
be exposed by God’s Holy Spirit to reveal the extent of sin’s ravages upon
us. It is, in effect, something like what happens whenever a machine scans the
inner organs and tissues of our bodies. It can show up not only what is healthy,
but what is cancerous and unwanted. It can see what the outer eye cannot.

When you get bitten by a snake, one of the best things you can do is to bring
its body with you (you will need to kill it first!) so that the poison can be
recognized, and the relevant antidote prescribed. It is the same with sin.
Unless we can identify (name) the poisons we will not know what the remedy will
be. It is not enough to be vague and general about our sins. Sins have names,
and we will do well to learn what they are. It will be a point of progress
whenever we can identify what those sins are that prevail in our lives. And
before we can do that, we will need to acknowledge that there is the need to do
it. Sin has got a hold of us in ways that we sometimes refuse to acknowledge. We
may be in some kind of denial about it. The point of inception is to face sin

Robert Murray McCheyne, the nineteenth century Scottish Presbyterian minister
whose life was extinguished before he reached thirty, wrote in his posthumously
published Diary: “I have begun to realize that the seeds of every
known sin still linger in my heart.” This is a point of advance.
Knowing this means that our eyes have been opened. Just like when a doctor
diagnoses what’s wrong and we come to appreciate the real need that exists.
Imagine a doctor saying to you: “Yes, there’s something going on inside
you, but we will not worry about that! Let’s look on the bright side, shall
we. Isn’t it a beautiful day!” What would you think of that? Even if that
satisfied your need for denial in the short term, I doubt that you would ever
visit that doctor again! Most of us, when things gets serious, want to know the
truth, even if it hurts. And hurt it will, make no mistake about that.

2. He identifies for us in detail what
needs to be dealt with.
There is a translation issue with our text that
needs to be looked at briefly. The New American Standard Version renders
verse 5 this way: “Consider the members of your earthly body as dead to…”
That sounds like something Paul says in Romans 6. There is a time to
“reckon ourselves to be dead to sin.” In Christ, the great change has
already taken place. But it is doubtful if that is Paul’s intention here.
Hence the New International Version renders it this way: “Put to
death, therefore, whatever belongs to your earthly nature”. This is better,
but it, too, disguises rather than clarifies what Paul intends here. Let me go
back to King James Version for a minute: “Put to death, therefore your
members which are on the earth
“. Probably the NIV translates it
that way lest we think that Paul is suggesting some sort of self-mutilation. The
Colossians were about to make that very mistake. But we do need to
appreciate that the way sin operates in our lives is via the members of
our body!

Your members! Christians need a physical holiness. New Testament
holiness transforms what we do with our bodies. It has eyes and hands and feet.

In fact, sin in the Christian life has the potency to destroy the individual
as well as others.

The first list of five sins moves from external acts to internal motivations.
It is staggering to think that the first thing Paul mentions is sexual immorality.
The word he uses covers all forms of prostitution, every illegitimate sexual
deviance, both heterosexual and homosexual or even bestial. He links with it the
attitude of the heart: impurity. By this he means us to consider that
what the mind will linger on in secret the body will do externally. Then comes lust,
that is, passions that come and master us, uncontrolled and uncontrollable. Desire
is the next word by which he means something which is out of control. And he
ends the list by suggesting that all sexual deviance is a form of greed,
which is a form of idolatry. These sins are selfish at their heart. They
show, as Calvin wrote in his 1559 edition of the Institutes of the Christian
: “Man’s mind is a perpetual factory of idols.” You have
lost your mind when you think that life is about satisfying what brings pleasure
to you, and you alone! You have made yourself like God when you think that way.
You are bowing down to the god of self.

Paul’s day was so remarkably like our own. It was day when sexual
immorality abounded. Homosexuality was as prevalent then as it is now. Paul’s
words here seem particularly pertinent for us today. Holiness, true holiness,
demands total sexual purity. Sin has distorted what God intended to be a
beautiful thing.

Perhaps this touches us very personally! Nobody else knows about it. Maybe,
that’s just as well. It would certainly make this sanctuary a very ugly place
if sexual sins were to be recited. Affairs, business trips, magazines, internet
pornography, the list of possible areas that affect us endless.

Put these sins to death! It will destroy you if you don’t. “Because of
these things the wrath of God is coming,” Paul adds. Frightening, isn’t
it! Do you notice that Paul has several motives for ethical living and not just
positive ones! In verses 1-4 the motive was positive. It is because of who we
are, of what we have become in Christ. We have died and have been raised with
Christ. Our lives are hidden with Christ in God. But here, the motive is
altogether negative. The wrath of God is coming on those who do not repent. Turn
or burn, is what Paul is suggesting, blunt and harsh as that may sound.

Sin also has a potential to destroy others. In verse 8, in what is another
list of five sins, Paul moves from internal emotions to external actions, doing
the opposite (or mirror image) of what he had done in verses.5-7. The five sins
mentioned are: anger, rage, malice, slander, and filthy language from your lips.
He begins with anger: that spirit of being opposed in a hostile way to
things that God desires for our lives. There is a righteous anger that is
perfectly proper and in accord with the highest reaches of holiness. But that is
not what Paul has in mind here. To understand what he means he adds, rage!
We hear of road rage, and the rage of a husband towards his wife. A seething
cauldron of rage. (One commentator suggests it can be translated as
“exasperation”). We sometimes regard exasperation as a virtue! We say,
“I don’t suffer fools gladly.” Flying off the handle. Then comes malice,
a refusal to forgive, and allied to cynicism. The comes slander: defaming
someone’s character or character assassination. It would be wonderful to say
the church was free from this kind of ting, but it is not. Paul is calling
Christians to be different from the world. Not to wag their tongues. If you
cannot think of something good to say about other people’s character, then say
nothing at all!

Jonathan Edwards had a daughter with an ungovernable temper. A young man
asked Edwards if he could marry her. “No!” he replied. Upon asking for
the reason, Edwards went on: “Because she is not worthy of you!”
adding, “the grace of God can live with some people with whom no one else
can live!”

Sex and speech, these are the features of life that are most out of control.
You will never grow until you bring the surgeon’s knife of God’s Word at
these points in your life. Maybe you are where Augustine was, praying:
“Give me chastity, but not yet!” And God is saying to you: I want it, now!

But is there is one more thing that Paul seems eager to say. Sin cannot
always be dealt with privately. In verse 9 he urges the Colossians not to lie.
He is not simply calling for truthfulness, but rather honesty and
accountability. Don’t pretend, he seems to be saying. If I am going to be able
to function in this fellowship, then I had better stop pretending that I am
better than I am. We need to be able to say to each other: “I need your
help, counsel, wisdom. I am struggling to Zion, rather than marching to

The way of pretence is a way that leads to failure in fellowship and
Christian living.

3. Practical indications as to how we go
about this
There are two verbs which Paul employs in the
passage that need to be engraved upon our hearts: “put to death” (v.5)
and “rid yourselves” (v.8). They bring to mind the words of Jesus in
the Sermon on the Mount that urge us to pluck out right eyes and sever right

“Let not that Christian think that he makes any progress in true
holiness who is not prepared to walk over the bellies of his lusts” wrote
Owen in his uncompromising way.

It may sound to you like legalism. That is a convenient word that some
Christians employ to shirk the task of painful self-examination and change. They
use this when some application sounds as though it will hurt. But it is not
legalism to want to be as holy as Jesus. It is the only sensible thing to
desire. Anything less is compromise and unworthy.

Without getting too technical, the tense of the verb (aorist imperative) has
in mind the whole action. Paul is concerned not simply with the resolve to
mortify sin, but the desire to be rid of it altogether. It is as if he was
saying: “Lay your hands on this sin’s throat and don’t release the
pressure until it stops breathing.”

What will that mean? It will begin with an honest owning up to the gravity of
our condition. It will mean facing sin down and pursuing its destruction at
whatever cost to ourselves. It will mean going before the Lord and saying:
“Lord, I have this besetting sin. And I am so sorry. I fly off the handle,
or I trash people, or I gossip all the time. I rejoice when others fall because
it makes me feel better about myself.” It will mean changing habits and
lifestyle, determined that our members be used for that which holy and not that
which is pandering to self-gratification at the expense of God’s Word and God’s

Will you pursue this task? Without it, we will always be less than what God
wants us to be.
