4 Surely He has borne our griefs and carried our sorrows; yet we esteemed Him stricken, smitten by God, and afflicted.
5 But He was wounded for our transgressions, He was bruised for our iniquities; the chastisement for our peace was upon Him, and by His stripes we are healed.
6 All we like sheep have gone astray; we have turned, every one, to his own way; and the LORD has laid on Him the iniquity of us all.

Isaiah 53:4-6

Verse 5 says, “The chastisement for our peace was upon Him.” The word “chastisement” means discipline, correction, and rebuke.

Colossians 1:21 refers to us as people who “once were alienated and enemies in your mind by wicked works.” To be “alienated” means to be estranged; to be a nonparticipant; to be cut-off from fellowship or intimacy. Jesus bore all the chastisement that we deserved for our rebellion so we could come back to the Father.

Imagine a shepherd who has a lot of sheep in his flock. He expects all of them to move in the direction he is leading them, but then one strays off this way and another goes off the other way. The ones that have strayed off are no longer in fellowship, or together with the rest of the pack; they are alienated. They are estranged. The shepherd has no control over whatever happens to them. The shepherd can only go after them, but they still have to decide to follow him. We were like that. Everyone had gone his own way. By wicked works in our minds we had alienated ourselves from God. We were not thinking like God, we were not talking like God, we were so different. Then Jesus came to reconcile us back to the Father. He came to make peace where there was enmity before. Peace means that we are now whole, complete and united with the Father; it means that there is nothing missing and nothing broken in our lives. We have been brought near by the blood of Christ.

Confession:

He was wounded for my transgressions; He was bruised for my iniquities; the chastisement of my peace was upon Him, and by His stripes I am healed.
