John Trapp on Psalms 6:9

Verſ. 9. The Lord hath heard my ſupplication] And thereby ſealed up ſweeteſt love to my Soul; as Ahaſhuerus afterwards did to his Heſter, by granting her requeſt. But how knew David, and how may another man in like ſort know that God hath heard his prayer, though as yet no viſible return appeareth?

I anſwer; This he may know.

1 By a caſt of Gods pleaſed countenance.

2 By the teſtimony of his own Conſcience, Phil. 4.6, 7. and by the aſſurance of faith, which faith to a man as the Angel once did to Cornelius, Thy prayers are heard and anſwered. Of Luther we read, that having been once wraſtling hard with God by prayer, for the proſperous proceeding of the Reformation in Germany, about which there was a general meeting of the States at that time, he came leaping out of his Cloſet with Vicimus, Vicimus, in his mouth, that is, we have prevailed, we have got the day. God ſometimes anſwereth his people before they pray, ſometimes whiles they are praying, as here, and ſometimes after they have prayed, but ſooner or later they ſhall be ſure of it.

The Lord will receive my prayer] He hath, and therefore he will. This is the Language of faith, this is the triumph of truſt.
