¹⁸ But what God foretold by the mouth of all the prophets, that this Christ should suffer, He thus fulfilled.
¹⁹ Repent therefore, and turn again, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord,
²⁰ and that He may send the Christ appointed for you, Jesus,   (RSV)

Acts 17:30

³⁰Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent,
³¹because 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.

We are saved by GRACE through FAITH. It must be a faith that is strong enough to lead us to REPENT of our sins.
