2 Timothy 1:3; 2 Timothy 2:18; 2 Timothy 3:8

2 Timothy 1:3

3 I thank God, whom I serve, as my ancestors did, with a clear conscience, as night and day I constantly remember you in my prayers.

2 Timothy 2:18

18 who have departed from the truth. They say that the resurrection has already taken place, and they destroy the faith of some.

2 Timothy 3:8

8 Just as Jannes and Jambres opposed Moses, so also these teachers oppose the truth. They are men of depraved minds, who, as far as the faith is concerned, are rejected.
