2 Timothy 2:10-13

Therefore I endure everything for the sake of the elect, that they too may obtain the salvation that is in Christ Jesus, with eternal glory. Here is a trustworthy saying: If we died with him, we will also live with him; if we endure, we will also reign with him. If we disown him, he will also disown us; if we are faithless, he remains faithful, for he cannot disown himself.
