Psalms 56:7

Be merciful unto me, O God. This petition includes all the good for which we come to throne of grace. If we obtain mercy there, we need no more to make us happy. It implies likewise our best plea, not our merit, but God's mercy, his free, rich mercy. We may flee to, and trust the mercy of God, when surrounded on all sides by difficulties and dangers. His enemies were too hard for him, if God did not help him. He resolves to make God's promises the matter of his praises, and so we have reason to make them. As we must not trust an arm of flesh when engaged for us, so we must not be afraid of an arm of flesh when stretched out against us. The sin of sinners will never be their security. Who knows the power of God's anger; how high it can reach, how forcibly it can strike?

Shall they escape by iniquity? Will such wickedness as this stand them in good stead? Can it be that this conduct shall enable them to avoid the sentence of earthly punishment? They slander the good man to screen themselves —will this avail them? They have cunningly managed hitherto, but will there not be an end to their games? In thine anger cast down the people, O God. Trip them up in their tricks. Hurl them from the Tarpeian rock. A persecuted man finds a friend even in an angry God, how much more in the God of love! When men seek to cast us down, it is but natural and not at all unlawful to pray that they may be disabled from the accomplishment of their infamous designs. What God often does we may safely ask him to do.
