“As for man, his days are like grass; as a flower of the field, so he flourishes. For the wind passes over it, and it is gone, and its place remembers it no more. But the mercy of the Lord is from everlasting to everlasting on those who fear Him, and His righteousness to children’s children, to such as keep His covenant, and to those who remember His commandments to do them.” – Psa. 103:15-18
Man is finite, but God is infinite and His mercy is conditional.
