2 Timothy 2:10-15

10Therefore I endure all things for the elect’s sake, that they also may obtain the salvation which is in Christ Jesus with eternal glory. 11Faithful is the saying: For if we died with him, we shall also live with him: 12if we endure, we shall also reign with him: if we shall deny him, he also will deny us: 13if we are faithless, he abideth faithful; for he cannot deny himself.

14Of these things put them in remembrance, charging them in the sight of the Lord, that they strive not about words, to no profit, to the subverting of them that hear. 15Give diligence to present thyself approved unto God, a workman that needeth not to be ashamed, handling aright the word of truth.
