God is lavish with his grace, so we can live guilt free. We can be secure in the knowledge that his supply of grace is sufficient for all our sins—past, present, and future. God gives his grace richly, freely, recklessly, plentifully, and ridiculously. He has a bottomless supply made available to us through the death and resurrection of his Son. This grace is a gift. We never have to lift a finger to earn it and it’s always available to us.
