By striving to prove how much they deserve God’s love, legalists miss the whole point of the gospel, that it is a gift from God to people who don’t deserve it. The solution to sin is not to impose an ever-stricter code of behavior. It is to know God.
and believing that God gives gifts to the undeserving, is a foundational flaw. The preequisite for receiving God's Love is to desires it in a state of humility.
