2 Timothy 2:11-15

Faithful is the saying: For if we died with him, we shall also live with him: if we endure, we shall also reign with him: if we shall deny him, he also will deny us: if we are faithless, he abideth faithful; for he cannot deny himself. Of 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. Give diligence to present thyself approved unto God, a workman that needeth not to be ashamed, handling aright the word of truth.
