O Thou that hearest prayer, unto Thee shall all flesh come. – Psalm 65:2

Prayer is always and habitually received of God. “O Thou that hearest prayer.” Not that didst hear it or on a certain occasion may have heard it, but Thou that ever hearest prayer. If He always hears prayer, then He always hears praise. Is not this delightful to think of my praise, though it be but that of a child or a poor unworthy sinner-God does hear it, does accept it, in spite of its imperfections, and does accept it always? Oh, I will have another hymn to-morrow, I will sing a new song to-morrow. I will forget my pain, I will forget for a moment all my care, and if I cannot sing aloud by reason of those that are with me, yet will I set the bells of my heart ringing, I will make my whole soul full of praise. If I cannot let it out of my mouth, I will praise Him in my soul, because He always hears me. You know it is hard to do things for one who never accepts what you do. Many a wife has said, “Oh! it is hard. My husband never seems pleased. I have done all I can, but he takes no notice of little deeds of kindness.” But how easy it is to serve a person who, when you have done any little thing, say, “How kind it was of you” and thinks much of it. Ah, poor child of God, the Lord thinks much of thy praises, much of thy vows, much of thy prayers. Therefore, be not slack to praise and magnify Him unceasingly.

And this all the more, because we have not quite done with that word, “Unto Thee shall all flesh come.” All flesh shall come because the Lord hears prayer. Then all my praises will be heard and all the praises of all sorts of men, if sincere, come unto God. The great ones of the earth shall present praise, and the poorest of the poor also, for Thou shalt not reject them. ~ C.H. Spurgeon
