2 Timothy 2:11-15

This is a faithful and trustworthy saying: If we died with Him, we will also live with Him; If we endure, we will also reign with Him; If we deny Him, He will also deny us; If we are faithless, He remains faithful [true to His word and His righteous character], for He cannot deny Himself. Remind the people of these facts, and solemnly charge them in the presence of God to avoid petty controversy over words, which does no good, and [upsets and undermines and] ruins [the faith of] those who listen. Study and do your best to present yourself to God approved, a workman [tested by trial] who has no reason to be ashamed, accurately handling and skillfully teaching the word of truth.
