2 Peter 3:9

2 Peter 3:9. The Lord in not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.

Therefore does he wait. If men ask why there is no interposition of wrath to overthrow the ungodly, the answer is, because this is part of God’s great reign of love. He waits, because he is "not willing that any should perish, but that all should come to repentance;" yet there will be a limit even to his patience.
