Why be a law-abiding citizen?
While it is certainly true that justification frees one forever from the need to keep the law, or try to, as the means of earning life, it is equally true that adoption lays on one the abiding obligation to keep the law, as the means of pleasing one’s newfound Father.
–J. I. Packer
Paul said to the church in Ephesus:
God saved you by his grace when you believed. And you can’t take credit for this; it is a gift from God. Salvation is not a reward for the good things we have done, so none of us can boast about it. We are God’s masterpiece. He has created us new in Christ Jesus, so we can do the good things he planned for us long ago.
Good works don’t get you into heaven with Jesus.
But once you have Jesus and have been adopted into the family by the loving God of all… you will want to do the good works that please Him!
Go out and “keep the law” doing the the things that honor God not to try to earn His love, but in gratitude for His great love that He has freely given to us.
