And you [who are in Christ], who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. — Colossians 2:13–14

Father: “My Son, here is a company of poor miserable souls, that have utterly undone themselves, and now lie open to my justice! Justice demands satisfaction for them, or will satisfy itself in the eternal ruin of them: What shall be done for these souls?” And thus Christ returns.

Son: “O my Father, such is my love to, and pity for them, that rather than they shall perish eternally, I will be responsible for them as their Surety; bring in all thy bills, that I may see what they owe thee; Lord, bring them all in, that there may be no after-reckonings with them; at my hand shalt thou require it. I will rather choose to suffer thy wrath than they should suffer it: upon me, my Father, upon me be all their debt.”

Father: “But, my Son, if thou undertake for them, thou must reckon to pay the last mite, expect no abatements; if I spare them, I will not spare thee.”

Son: “Content, Father, let it be so; charge it all upon me, I am able to discharge it: and though it prove a kind of undoing to me, though it impoverish all my riches, empty all my treasures, (for so indeed it did, ‘Though he was rich, yet for our sakes he became poor’ [2 Cor 8:9]) yet I am content to undertake it.”
