2 Timothy 2:8–13

8 Remember Jesus Christ, risen from the dead, the offspring of David, as preached in my gospel, 9 for which I am suffering, bound with chains as a criminal. But the word of God is not bound! 10 Therefore I endure everything for the sake of the elect, that they also may obtain the salvation that is in Christ Jesus with eternal glory. 11 The saying is trustworthy, for:

  If we have died with him, we will also live with him;
12   if we endure, we will also reign with him;
  if we deny him, he also will deny us;
13   if we are faithless, he remains faithful—

for he cannot deny himself.
