Watch your life and your doctrine closely

"set the believers an example in speech, in conduct, in love, in faith, in purity. Until I come, devote yourself to the public reading of Scripture, to exhortation, to teaching.

Do not neglect the gift you have, which was given you by prophecy when the council of elders laid their hands on you.  Practice these things, devote yourself to them, so that all may see your progress.

Keep a CLOSE WATCH on yourself and on the teaching.  Persist in this, for by so doing you will save both yourself and your hearers."

Paul's 1st letter to Timothy, Chapter 4, verses 12 - 16
