In Gods case, if He had said in the infinite sovereignty of His absolute will, "I will have no substitute, but each man shall suffer for himself, he who sinneth shall die," none could have murmured. It was grace, and only grace which led the divine mind to say, "I will accept of a substitute. There shall be a vicarious suffering; and My vengeance shall be content, and My mercy shall be gratified."
If you are ready to partake of grace you have not to atone for your sins--you have merely to accept of the atonement. All that you want to do is to cry, "God have mercy upon me," and you will receive the blessing.
The purpose of our holy and righteous God was to save His church, but their sin could not go unpunished. It was, therefore, necessary that the punishment for that sin be transferred from those who deserved it but could not bear it, to one who did not deserve it but was able to bear it.
