Psalms 66:20

"Blessed be my God, that has not thrust away my supplication and His mercy from me" [Psalm 66:20]. Gather the sense from that place, where he says, "Come ye, hear, and I will tell you, all you that fear God, how great things He has done to my soul:" he has both said the words which you have heard, and at the end thus he has concluded: "Blessed be my God, that has not thrust away my supplication and His mercy from me." For thus there arrives at the Resurrection he that speaks, where already we also are by hope: yea both it is we ourselves, and this voice is ours. So long therefore as here we are, this let us ask of God, that He thrust not from us our supplication, and His mercy, that is, that we pray continually, and He continually pity. For many become feeble in praying, and in the newness of their own conversion pray fervently, afterwards feebly, afterwards coldly, afterwards negligently: as if they have become secure. The foe watches: you sleep. The Lord Himself has given commandment in the Gospel, how "it behooves men always to pray and not to faint." And he gives a comparison from that unjust judge, who neither feared God, nor regarded man, whom that widow daily importuned to hear her; and he yielded for weariness, that was not influenced by pity: and the naughty judge says to himself, "Though neither God I fear, nor men I regard, even because of the weariness which this widow daily puts upon me, I will hear her cause, and will avenge her." And the Lord says, "If a naughty judge has done this, shall not your Father avenge His chosen, that to Him do cry day and night? Yea, I say unto you, He shall make judgment of them speedily." Therefore let us not faint in prayer. Though He puts off what He is going to grant, He puts it not away: being secure of His promise, let us not faint in praying, and this is by His goodness. […]

This he adds by way of correction: "It was not my prayer that fetched the deliverance, but his mercy that sent it." Therefore God does not turn away our prayer, because he does not turn away his own mercy, for that is the foundation of our hopes and the fountain of our comforts, and therefore ought to be the matter of our praises.

If we have learned in every thing to give thanks for ancient and modern mercies, public and personal mercies, we shall know how to sing this psalm with grace and understanding. All Mankind Exhorted to Praise God. 1 Make a joyful noise unto God, all ye lands: 2 Sing forth the honour of his name: make his praise glorious.

With these he unites his public thanks, inviting those who fear God (Ps 60:4; 61:5, His true worshippers) to hear. He vindicates his sincerity, inasmuch as God would not hear hypocrites, but had heard him.

Blessed be God. Be his name honoured and loved. Which hath not turned away my prayer, nor his mercy from me. He has neither withdrawn his love nor my liberty to pray. He has neither cast out my prayer nor me. His mercy and my cries still meet each other. The psalm ends on its key note. Praise all through is its spirit and design. Lord enable us to enter into it. Amen.
