30 Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, 31 because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead. (Acts 17:30–31)
God is longsuffering and just. His character demands that He righteously judge and punish sin – God does not ignore sin. His character compels Him to offer merciful forgiveness by commanding all sinners everywhere to repent and thereby escape His wrath against sinners. So, rather than immediately intercede with punishment against sin, God commands repentance while assuring us there will be a day of judgment, and the Man God raised from the dead will be that judge; Jesus. If you want to escape divine punishment for your sins then you must obey God and repent. Do it now. One day God’s longsuffering will end and His judgment will begin (2 Pet. 3:9-10).
