Charles H. Spurgeon on Psalms 30:9

In this verse we learn the form and method of David's prayer. It was an argument with God, an urging of reasons, a pleading of his cause. It was not a statement of doctrinal opinions, nor a narration of experience, much less a sly hit at other people under pretence of praying to God, although all these things and worse have been substituted for holy supplication at certain prayer meetings. He wrestled with the angel of the covenant with vehement pleadings, and therefore he prevailed. Head and heart, judgment and affections, memory and intellect were all at work to spread the case aright before the Lord of love. What profit is there in my blood, when I go down to the pit? Wilt thou not lose a songster from thy choir, and one who loves to magnify thee? Shall the dust praise thee? shall it declare thy truth? Will there not be one witness the less to thy faithfulness and veracity? Spare, then, thy poor unworthy one for thine own name sake!
