TRUE REPENTANCE

2 Peter 3:9-10
9 The Lord does not delay and is not tardy or slow about what He promises, according to some people's conception of slowness, but He is long-suffering (extraordinarily patient) toward you, not desiring that any should perish, but that all should turn to repentance.
10 But the day of the Lord will come like a thief, and then the heavens will vanish (pass away) with a thunderous crash, and the [material] elements [of the universe] will be dissolved with fire, and the earth and the works that are upon it will be burned up.
