12. Our Lord and Master, and Saviour, knowing this dangerous temptation in this life, when He taught us six or seven petitions in this Prayer, took none of them for Himself to treat of, and to commend to us with greater earnestness, than this one. Have we not said, “Our Father, which art in heaven;” and the rest which follows? Why after the conclusion of the Prayer, did He not enlarge upon it to us, either as to what He had laid down in the beginning, or concluded with at the end, or placed in the middle? For why said He not, if the Name of God be not hallowed in you, or if ye have no part in the kingdom of God, or if the will of God be not done in you, as in heaven, or if God guard you not, that ye enter not into temptation; why none of all these? but what saith He? “Verily I say unto you, that if ye forgive men their trespasses;” in reference to that petition, “Forgive us our debts, as we also forgive our debtors.” Having passed over all the other petitions which He taught us, this He taught us with an especial force. There was no need of insisting so much upon those sins in which if a man offend, he may know the means whereby he may be cured: need of it there was, with regard to that sin in which if thou sin, there is no means whereby the rest can be cured. For this thou oughtest to be ever saying, “Forgive us our debts.” What debts? There is no lack of them; for we are but men; I have talked somewhat more than I ought, have said something I ought not, have laughed more than I ought, have eaten more than I ought, have listened with pleasure to what I ought not, have drunk more than I ought, have seen with pleasure what I ought not, have thought with pleasure on what I ought not; “Forgive us our debts, as we also forgive our debtors.” This if thou hast lost, thou art lost thyself.
