[16] All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, [17] that the man of God may be competent, equipped for every good work.
[4:1] I charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by his appearing and his kingdom: [2] preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching. [3] For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, [4] and will turn away from listening to the truth and wander off into myths. (2 Timothy 3:16-4:4 ESV)

Who is God’s messenger in your church?  Nearly every response will likely be “my preacher” or “my pastor.” Which is the correct response!  What does he think of the Bible?  Is it THE source of his messages from God?  Does he turn to it when offering counsel?  Does he use it when he teaches?  Is he a student of the Word?  If the answer to these questions is yes, thenbased on 1 Timothy 3:17 he is competent and equipped for every good work.
Consider the charge in 4:1-4:  Paul’s charge to Timothy and every messenger of God is to preach the word and be always ready.  Additionally he is charged to reprove, rebuke, and exhort — all with complete patience and teaching.
Paul told Timothy that the time is coming when people will not endure sound teaching but will look to teachers (and preachers) to satisfy their own desires (what they want to hear).  So this note of prophecy is that these same people will turn away from listening to the truth and wander off into myths.
Over the last century we have seen the progression of this wandering off mentioned in verse 4. One can generate a large crowd of people with a message that is riddled with myth.  There are
the seekers of a message that will tickle their ears.  So we must be aware of the reality that a man or woman who can pack out large civic centers are not necessarily presenting a message of truth.  There is a market for myth today.  It was prophesied and we are seeing it fulfilled in our lifetime.
God’s messenger is charged to present the truth of the message which will include a message about sin (reprove and rebuke) as well as more positive messages of promise, hope and comfort (exhorting).
In our self-esteemed-bloated society, we want to avoid the discussion of sin.  Yet, friend, one cannot…I repeat…cannot come to God without dealing with the question of sin in one’s life.  It was the very reason Christ came to die!
But if we confess our sins to him, he is faithful and just to forgive us our sins and to cleanse us from all wickedness. (1 John 1:9)
