Psalms 66:20

Blessed be God, which hath not turned away my prayer - That is, It is fit that I should praise and adore God for the fact that he has graciously condescended to listen to the voice of my supplications.

Nor his mercy from me - There is no more proper ground of praise than the fact that God hears prayer - the prayer of poor, ignorant, sinful, dying men. When we consider how great is his condescension in doing this; when we think of his greatness and immensity; when we reflect that the whole universe is dependent on him, and that the farthest worlds need his care and attention; when we bear in mind that we are creatures of a day and “know nothing;” and especially when we remember how we have violated his laws, how sensual, corrupt, and vile our lives have been, how low and grovelling have been our aims and purposes, how we have provoked him by our unbelief, our ingratitude, and our hardness of heart - we can never express, in appropriate words, the extent of his goodness in hearing our prayers, nor can we find language which will properly give utterance to the praises due to his name for having condescended to listen to our cries for mercy.
