Grace is More Abundant and Stronger than Sin

Luther, lecturing on Galatians 4:6--

Now, we are sure that Christ pleases God, that he is holy and so on. Inasmuch, then, as Christ pleases God and we are in him, we also please God and are holy.

Although sin still remains in us, and although we daily fall and offend, grace is more abundant and stronger than sin. The mercy and truth of the Lord reign over us forever. Therefore, sin cannot make us afraid or make us doubt God's mercy in us. For Christ, that most mighty giant, has abolished the law, condemned sin, and vanquished death and all evils.

So long as he is at the right hand of God making intercession for us, we cannot doubt God's grace and favor toward us.

--Martin Luther, Galatians (Crossway, 1998), 205
