“In whom we have redemption through [Christ’s] blood, the forgiveness of sins, according to the riches of his grace” (Eph. 1:7).
The climax of Paul’s first recorded sermon is reached in Acts 13, where he declares:
“Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins: And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses” (Acts 13:38,39).
Thus God through Christ, forgives and justifies those who believe. Nor is this all that was accomplished for us by the death of Christ at Calvary. There is also reconciliation, baptism by the Spirit into Christ and His Body, a position at God’s right hand in the heavenlies and all spiritual blessings there.
“The forgiveness of sins” must come first, however, and the above passage assures us that in Christ we have this — not barely, but “ACCORDING TO THE RICHES OF HIS GRACE”. Indeed, the next verse continues: “WHEREIN HE HATH ABOUNDED TOWARD US…”
Thus Ephesians 2:2-7 declares that though we were once “the children of disobedience”, and therefore “by nature the children of wrath”, “God, WHO IS RICH IN MERCY, for His GREAT LOVE wherewith He loved us”, has given us life and raised us from the dead, exalting us to “heavenly places in Christ…”
His purpose in all this? “THAT IN THE AGES TO COME HE MIGHT SHOW THE EXCEEDING RICHES OF HIS GRACE IN HIS KINDNESS TOWARD US THROUGH CHRIST JESUS” (Eph. 2:7).
When God forgives us He no longer sees us in our poor selves, BUT IN CHRIST, who took our place, dying for our sins on Calvary’s cross. There He hung in our place that we might now stand in His — “COMPLETE IN HIM” (Col. 2:10). source
