Day of the Lord & The Offer of Mercy

A New Testament passage that describes this messages: 2 Peter 3:9-10 (ESV), "The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance. 10 But the day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies will be burned up and dissolved, and the earth and the works that are done on it will be exposed. "
