God's solution to our problem was to become what our problem was. Our problem wasn't our humanity, it wasn't our environment, our parents, our schooling, which side of the tracks we grew up on, or what we had or didn't have. Our problem was always a spiritual problem: our problem was sin. Jesus became that problem. And not only did He do something amazing about it, He did something amazing to us.
2 Cor 5:21 God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.
