2 Timothy 2:10-13

10Therefore I endure everything for the sake of the elect, that they too may obtain the salvation that is in Christ Jesus, with eternal glory.

11Here is a trustworthy saying: If we died with him, we will also live with him;

12if we endure, we will also reign with him. If we disown him, he will also disown us;

13if we are faithless, he remains faithful, for he cannot disown himself.
