Paul's claim in our text, for example, would be the worst sort of hypocrisy in such a case. Peter said: "Wherefore laying aside all malice, and all guile, and hypocrisies, and envies, and all evil speakings, As newborn babes, desire the sincere milk of the word" (1 Peter 2:1-2). John warned: "All liars, shall have their part in the lake which burneth with fire and brimstone" (Revelation 21:8).
All the apostles and writers of the New Testament (except John, who also suffered severe persecution throughout his long life) eventually died as martyrs for their faith, and it is incredible that they would have suffered and died for a message they knew to be a lie. We can have complete confidence that the New Testament records are honest reports of sincere and godly men. HMM
