2 Timothy 2:13-17

If we are not faithful, he will still be faithful, because he must be true to who he is. Continue teaching these things, warning people in God’s presence not to argue about words. It does not help anyone, and it ruins those who listen. Make every effort to give yourself to God as the kind of person he will approve. Be a worker who is not ashamed and who uses the true teaching in the right way. Stay away from foolish, useless talk, because that will lead people further away from God. Their evil teaching will spread like a sickness inside the body. Hymenaeus and Philetus are like that.
