The answer is found in Acts 17:30-31:
βTruly, these times of ignorance God overlooked, but now commands all men everywhere to repent, 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.β
Jesus' resurrection from the dead after dying as a sacrificial lamb is proof that God has accepted Him. Also there is Hebrews 10:12:
But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God,
Jesus sitting at God's right hand also vindicates His sacrifice. God has a place for Him right at His side.
