His nation was full of blind transgressors whose sins had separated themselves from him. So, God picks up his own armor, and brings redemption himself. This is the message of Romans 1-3. It is the story of a God who loved his people so much that even after they refused the life he promised, he made a way for them to be restored. Then he assured that these same rebellious people would preserve the promise of this salvation: the Old Testament.
LORD, thank you for loving your people, and making a way for all people to come to you.
Isaiah 59
