Charles H. Spurgeon on Psalms 65:2

O thou that hearest prayer, etc. This is one of his titles of honour, he is a God that hears prayer; and it is as truly ascribed to him as mercy or justice. He hears all prayer, therefore, unto thee shall all flesh come. He never rejects any that deserves the name of prayer, how weak, how unworthy soever the petitioner be. All flesh! And will he (may faith say) reject mine only? Ro 10:12, "He is rich unto all that call upon him; " Ps 86:5, "Thou art plenteous in mercy to all that call upon thee; "Heb 11:6, "A rewarder of them that diligently seek him." This must be believed as certainly as we believe that God is. As sure as God is the true God, so sure is it that none who sought him diligently departed from him without a reward. He rewards all seekers, for indefinita in materia necessaria aequipollet universali. And if all, why not me? You may as well doubt that he is God, as doubt that he will not reward, not hear prayer; so Jas 1:5, "If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him." David Clarkson.
