Charles H. Spurgeon on Psalms 138:2

For thou hast magnified thy word above all thy name. This is one of those expressions of Scripture that seem so comprehensive, and yet so amazing. To my mind it is one of the most remarkable expressions in the whole book of God. "Thou hast magnified thy word above all thy name." The name of God includes all the perfections of God; everything that God is, and which God has revealed himself as having —his justice, majesty, holiness, greatness, and glory, and whatever he is in himself, that is God's name. And yet he has "magnified" something "above his name" —his word —his truth. This may refer to the Incarnate Word, the Son of God, who was called "the Word." "There are three that bear record in heaven, the Father, the Word, and the Holy Ghost, and these three are one": 1Jo 5:7, "In the beginning was the Word, and the Word was with God": Joh 1:1. You may take the words either as meaning that God has magnified his Word, his eternal Son —above all his great name, that is, he has set Jesus on high above all the other perfections of his majesty; or take it as meaning his written word, which is written in the sacred Scriptures. So, in that case, not only the Incarnate Word in the person of Jesus; but also the written word in the Scriptures of truth. He has magnified it above all his name in the fulfilment of it: God's faithfulness being so dear to him, he has exalted his faithfulness above all his other perfections. We see this in nature. Here is a man so to be depended upon, so faithful to his word, that he will sacrifice anything sooner than depart from it: that man will give up his property, or life itself, rather than forfeit his word. So God has spoken of magnifying his word above all his name. He would sooner allow all his other perfections to come to naught, than for his faithfulness to fail. He has so magnified his faithfulness, that his love, his mercy, his grace, would all sooner fail than his faithfulness —the word of his mouth and what he has revealed in the Scripture. What a firm salvation, then, is ours, which rests upon his word, when God has magnified that word above all his name! What volumes of blessedness and truth are contained therein! so that, if God has revealed his truth to your soul, and given you faith to anchor in the world of promise, sooner than that should fail, he would suffer the loss of all; for he has magnified his word above all his name. —Joseph C. Philpot.
