In atonement, there are two primary questions that are asked: (1) what does atonement through Jesus Christ accomplish in regards to our sins and (2) how does atonement work? Briefly, I want to put forward an answer the the first question. Atonement is where the death Christ through the Spirit simultaneously (1) instructs the believer about God and His righteous purposes and (2) redeems the believer from their sin. Both work together as two sides of the same coin in Jesus Christ.
If correct, the implication of this, then, is to come up with a theory of atonement that accounts for both instruction and redemption, and not just simply redemption as most accounts focus upon. This inclusion of instruction into the understanding of the atonement of Christ is warranted in light of Isaiah 53.5c reading more appropriately from the Hebrew: “upon his was the discipline (מוּסַ֤ר) that made us whole,” which corresponds to the LXX: “the instruction (παιδεία) of our shalom was upon him.”
