Matthew 18:25

But forasmuch as he had not to pay
Every sinner is insolvent; sinful man has run out the whole stock of nature, and is become a bankrupt, and has nothing to offer by way of composition; nor has he any righteousness to answer for him, nor any works of righteousness which deserve that name: and if he had, these are nothing in point of payment: for a debt of sin cannot be discharged by a debt of obedience; since God has a prior right to the latter; and in paying it, a man does but what is his duty. Sin being committed against an infinite God, contracts the nature of an infinite debt, which cannot be paid off by a finite creature. Christ only was able to pay this debt, and he has done it for his people; and without an interest in his blood, righteousness, and satisfaction, every debtor is liable to be cast, and will be cast into the prison of hell, there to lie till the uttermost farthing of the ten thousand talents is paid, which will be to all eternity. We see what a sad condition sin has brought men into; it has stripped them of their estates and possessions; it has reduced them to want and beggary; it exposes them to a prison; to the just resentments of their creditor; to the wrath of God, and the curses of the law; and what little reason there is to think, yea, how impossible it is, that a man should be able to merit anything at the hands of God, to whom he is so greatly indebted: he must first pay his debts, which is a thing impracticable, before he can pretend to do anything deserving the notice of God; and even was he set free, and clear of all his debts, and entered upon a new life of obedience, and this strictly attended to, without contracting any debts for the future, yet all this would be but what is due to God, and could merit nothing of him; see ( Luke 17:10 ) ( Romans 11:35 ) . We see also from hence, how much the saints are obliged to Christ Jesus, and how thankful they should be to him, who became a surety for such insolvent creatures; has paid all their debts for them, and procured for them every blessing of grace they stand in need of: but think, O sinner, what thou wilt be able to say and do, when God comes to reckon with thee, and thou hast nothing to pay, nor any to pay for thee, or be thy surety; a prison must be thy portion ever.

His Lord commanded him to be sold, and his wife and children, and all
that he had;
according to the Jewish laws, in such a case: of a man's being sold, or selling himself when poor, see ( Leviticus 25:47 ) , for the law in ( Exodus 22:3 ) , referred to by some as an instance of this, respects the selling of a man for theft, and not for debt. Of the selling of a man's wife for the payment of his debts, I do not remember to have read any law concerning it, or instances of it; but of children being taken for bondmen by the creditor, for their father's debts, mention is made, ( 2 Kings 4:1 ) . These children, by the Jewish writers {i}, are said to be the children of Obadiah, who contracted the debt to feed the prophets in a cave, when they were persecuted by Jezebel; and the creditor, according to them, was Jehoram, the son of Ahab, who lent him money on usury for this purpose, in his father's time; and now Obadiah being dead, he takes his children for the debt, and makes them bondmen; see also ( Nehemiah 5:5 ) . There seems to be an allusion to this practice, in ( Isaiah 50:1 ) , and it was not only the custom of the Jews to come upon children for the debts of parents, but of other nations: with the Athenians, if a father could not pay his debts, the son was obliged to pay, and in the mean while to be kept in bonds till he did {k}: and as Grotius, in ( 2 Kings 4:1 ) proves from Plutarch and Dionysius Halicarnassensis, children were sold by the creditors of their parents, as in Asia, at Athens, and at Rome. Now this expresses the state of bondage, sin, as a debt, brings men into; they become slaves to their own lusts, vassals of Satan, and in bondage to the law; and also the ruin and destruction it exposes them to; as, the curse and condemnation of the law, the wrath of God, eternal death, even the destruction of body and soul in hell:

and payment to be made
by punishment, which will always be making, and never finished. This order of the king was not intended to be executed, as the sequel shows; but declares the will of God, that the sad and woeful condition of man should be set before him by the ministers of the word; signifying what his state is, how deserving of vengeance, and what must be his portion, if grace prevent not: the view of which is to vindicate the rights of law and justice, to express the sinner's deserts, and move him to apply to the Lord for grace and mercy, which effect it had.
