It’s silly when the law is used in place of grace to address sin in the life of a believer. In Galatians 2:20 Paul says, “I have been crucified with Christ; it is no longer I who live, but Christ lives in me.”
This is why it’s illogical to use the law when the law not only failed to justify, but has already taken you as far as it can! The law successfully did its job! It condemned you a sinner, sentenced you to death, and then executed you.
This is what Paul means when he says, “I have been crucified with Christ…” While the law sentenced you to death Jesus took your place, your sin, to satisfy your debt, so that you could be justified before God! Jesus was crucified for you as you!
And this work of Jesus stands accomplished… Paul even uses the past tense: “I have been!” It’s done! What Jesus did for you on the cross was a permanent, lasting work! Your debt was paid and His righteousness was placed onto your account so that you stand today and forevermore justified!
This is why “it is no longer you who lives, but Christ lives in you!” While legalism challenges you to “give your life to Christ, so He can live in you…” the Gospel declares that “He gave His life for you, so you can live in Him!” You not only died with Christ, but were resurrected with Him!
Jesus now lives in you and works through you making the law pointless. By faith through grace you’ve associated with His death so that now you can walk in His life! Friend, grace really does change everything.
