2nd Timothy 2:20-26

One of the reasons a Christian should strive to be a workman approved when it comes to the word of God is so that they can be better used according to the purposes of God. An informed, well-grounded but humble believer will be of more use than an ignorant, belligerent, and opinionated false believer or carnal believer, but the mystery and surprising thing is the false or carnal believer may still be of some use which is what the text discusses today.
