For not he that commendeth himself is approved, but whom the Lord commendeth.
I’ve worked at places where each year you have to do a self-evaluation. Part of that evaluation is to tell management just how good you are, and what a lot of good things you did during the past year. The better you sound, the better salary raise you’ll get. In the Christian life, we are exhorted to take a quiet place. Let the Lord promote us if He wants to but we shouldn’t promote ourselves. There were many while the Lord was on earth that “approved” themselves by showing everyone how pious and godly they were. But the Lord Jesus called them “hypocrites”, “full of extortion and excess.” Pretty strong words. Let the Lord do the commending.
