“Was it difficult to save sinners, and yet maintain the rights of the divine government, and the honour of the law? See how this difficulty is removed by the obedience and death of Christ!
Now it appears, that the rights of the divine government are so sacred and inviolable, that they must be maintained, though the darling Son of God should fall a sacrifice to justice; and that not one offence against this government can be pardoned, without His making a full atonment. Now it appears that the Supreme Ruler is not to be trifled with, but that his injured honour must be repaired, though at the expense of His Son’s blood and life.
Now, the precept of the law is perfectly obeyed in every part, and a full equivalent to its penalty endured, by a person of infinite dignity; and it is only upon this footing, that is, of complete satisfaction to all the demands of the law, that any of the rebellious sons of men can be restored into favour.
This is a satisfaction which Christ alone could give: to sinners it is utterly impossible, either by doing or suffering. They cannot do all things that are written in the law; nor can they endure its penalty, without being for ever miserable: and therefore the law has received a more complete satisfaction in Christ than it would ever receive from the offenders themselves.”
