There was a relationship between our Lord and his people, which is too often forgotten, but which rendered it natural that he should bear the sin of his people. Why does the text speak of our sinning like sheep? I think it is because it would call to our recollection that Christ is our Shepherd. It is not, my brethren, that Christ took upon himself the sins of strangers. Remember that there always was a union of a most mysterious and intimate kind between those who sinned and the Christ who suffered. What if I say that it is not unjust but according to law that when a woman gets into debt her husband should bear it? And with the church of God sinning, it was but right that her Husband, who had espoused her unto himself, should become the debtor on her behalf. The Lord Jesus stood in the relationship of a married husband unto his church, and it was not, therefore, a strange thing that he should bear her burdens. It was natural for the next of kin to redeem the inheritance, it was most seemly that Immanuel, the next of kin, should redeem his lost church by his own blood. Recollect that there was a union closer even than the marriage bond, for we are members of his body. You shall not punish this hand of mine without making the sentient nature which dwells in the brain to suffer therewith; and does it seem strange to you that when the inferior members of the body have transgressed, the Head should be made to suffer? It seems to me, my brethren, that while substitution is full of grace, it is not unnatural, but according to the laws of everlasting love.
For meditation: The identification of the Lord Jesus Christ with sinners whom he would call his brothers was entirely appropriate (Matthew 3:13–15; Hebrews 2:10–14,17). For God to forgive repentant sinners is not a matter of justice abandoned but of justice applied (1 John 1:9).
