Charles H. Spurgeon on Psalms 65:5

By terrible things in righteousness wilt thou answer us. The reason why he answers thus is, because what God doth for his people, take one thing with another, is still in order to the crucifying of the flesh; and what more terrible than such a death? We pray for pleasing things, as we imagine, but as we are flesh as well as spirit; so the flesh hath still a part in every prayer, and what we beg is partly carnal, and upon the matter, in part, we beg we know not what. Now, the answer as it comes from God, take all together, is spiritual, which is a crucifying thing to sinful flesh; hence comes all the terror... You pray for pardon; that is a pleasing thing, yet rightly understand not pleasing to the flesh; it mortifies corruption, breaks the heart, engages to a holy life: every answer from our God to us, one way or the other, first or last, shall tend that way. God useth so to give good things unto his children, as withal to give himself, and show to them his heavenly glory in what is done... Now God is terrible to sinful flesh: so far as he appears, it dies. Jacob, therefore, whilst he conquered God in prayer, himself was overcome, signified by that touch upon his thigh put out of joint, where the chiefest stress in wrestling lies. When we are weak, then are we strong; because, as God appears, we die unto ourselves and live in him. William Carter, in a Fast Sermon entitled, "Light in Darkness." 1648.
