Charles H. Spurgeon on Psalms 71:16

I will go in the strength of the Lord God. Our translators give us a good sense, but not the sense in this place, which is on this wise, "I will come with the mighty deeds of the Lord Jehovah." He would enter into those deeds by admiring study, and then, wherever he went, he would continue to rehearse them. He should ever be a welcome guest who can tell us of the mighty acts of the Lord, and help us to put our trust in him. The authorised version may be used by us as a resolve in all our exertions and endeavours. In our own strength we must fail; but, when we hear the voice which saith, "Go in this thy might, "we may advance without fear. Though hell itself were in the way, the believer would pursue the path of duty, crying: I will go in the strength of the Lord God: I will make mention of thy righteousness, even of thine only. Man's righteousness is not fit to be mentioned —filthy rags are best hidden; neither is there any righteousness under heaven, or in heaven, comparable to the divine. As God himself fills all space, and is, therefore, the only God, leaving no room for another, so God's righteousness, in Christ Jesus, fills the believer's soul, and he counts all other things but dross and dung "that he may win Christ, and be found in him, not having his own righteousness which is of the law, but the righteousness which is of God by faith." What would be the use of speaking upon any other righteousness to a dying man? and all are dying men. Let those who will cry up man's natural innocence, the dignity of the race, the purity of philosophers, the loveliness of untutored savages, the power of sacraments, and the infallibility of pontiffs; this is the true believer's immovable resolve: "I will make mention of thy righteousness, even of thine only." For ever dedicated to thee, my Lord, be this poor, unworthy tongue, whose glory it shall be to glorify thee.
