Here surely is how Christ sanctified our humanity: by living a human life with all the practical choices and decisions of every day, and with all the outer demands and all the inner pressures and weakness of mortal humanity living in a fallen world in this present evil age. He took our sin, but in no way was he sinful. He entered into our slavery, but in no way was he enslaved. He entered into our pollution, but in no way was he defiled. Rather he sanctified not only our human nature in his nativity but also our human life by his consistent and continuously holy living. Having become one of us, a member of our sinful human race, “sinful flesh” (Rom 8:3), he not only sanctified our human nature in his own Person, but so sanctified human personal life that it became possible for us too to live as he did as genuinely compassionate and holy persons. It was under these conditions, we must conceive, that he sanctified our human life by consistently selfless, God-centered choices, which ultimately were to lead him inevitably to the cross.
