The hymn writer Anne Cousin wrote, “Jehovah lifted up His rod; O Christ, it fell on Thee! Thou wast sore stricken of Thy God; There’s not one stroke for me. Thy tears, Thy blood, beneath it flowed; Thy bruising healeth me.”
Why did Jehovah lift his rod and strike Christ? It was because Christ was our substitute on the cross. This is the heart of the cross. 1 Peter 3:18 says, “For Christ also suffered once for sins, the righteous for the unrighteous”. Christ suffered for the unrighteous. This means that the punishment he received was the penalty they deserved. Paul, in 2 Cor. 5:21, tells us that Christ was made sin for us so we could be made the righteousness of God in him. Christ was made sin.
