Can justice be satisfied if one man serves a sentence on behalf of another, even if this is done voluntarily? The answer is obvious. The demands of justice could not and cannot be satisfied by the wrong man suffering on behalf of the one who has committed the crime. We do not need to look to the laws of our nations to determine this, for our hearts tell us this is so. God has imprinted the demand for justice into the human conscience.
And yet this is just what happened with Jesus Christ, is it not? Jesus committed no sin, and yet He suffered for my sin so that I can be declared righteous. Was this a grave miscarriage of justice or was this, as the Bible indicates, a perfect expression of both mercy and justice? And if John Mark Karr cannot satisfy justice’s demands on behalf of the man who really killed JonBenet Ramsey, why is it that Jesus can satisfy justice’s demands on behalf of the man who actually did?
