2nd Timothy 2:15

12 if we endure, we shall also reign with him: if we shall deny him, he also will deny us:

13 if we are faithless, he abideth faithful; for he cannot deny himself.

14 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.

15 Give diligence to present thyself approved unto God, a workman that needeth not to be ashamed, handling aright the word of truth.

16 But shun profane babblings: for they will proceed further in ungodliness,

17 and their word will eat as doth a gangrene: or whom is Hymenaeus an Philetus;

18 men who concerning the truth have erred, saying that the resurrection is past already, and overthrow the faith of some.
