Charles Spurgeon Commentary 2 Timothy 2:12-13

"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." — 2 Timothy 2:12-13 (ASV)

It is a faithful saying: For if we be dead with him, we shall also live with him: If we suffer, we shall also reign with him: if we deny him, he also will deny us: If we believe not, yet he abideth faithful: he cannot deny himself.

Glory be to God, the unbelief of man cannot make God break His promises. Christian, all your unbelief has not made God unfaithful to you: and sinner, though you cast out the promise of God as being good for nothing, yet He will not therefore abolish the recompense of reward, for Jesus will save others if He does not save you.

"He abideth faithful."
