Open defiance
In the meantime, while we do not from our hearts forgive our neighbor his trespasses, what manner of prayer are we offering to God whenever we utter these words? We are indeed setting God at open defiance. We are daring him to do his worst. Forgive us our trespasses, as we forgive those who trespass against us. That is, in plain terms, Do not forgive us at all. We desire no favor at your hands. We pray that you will keep our sins in remembrance, and that your wrath may abide upon us. But can you seriously offer such a prayer to God? And has he not yet cast you alive into hell? O tempt him no longer. Now, even now, by his grace, forgive as you would be forgiven. Now have compassion on your fellow servant (Matthew 18:33), as God has had, and will have, pity on you.

In the mean time, while we do not from our hearts, forgive our neighbour his trespasses, what manner of prayer are we offering to God, whenever we utter these words? We are indeed setting God at open defiance: we are daring him to do his worst. Forgive us our trespasses, as we forgive them that trespass against us! That is in plain terms, “Do not thou forgive us at all: we desire no favour at thy hands. We pray, that thou wilt keep our sins in remembrance, and that thy wrath may abide upon us.” But can you seriously offer such a prayer to God? And hath he not yet cast you quick into hell? O tempt him no longer! Now, even now, by his grace, forgive as you would be forgiven! Now have compassion on thy fellow-servant, as God hath had and will have pity on thee.
