Charles H. Spurgeon on Psalms 119:111

Thy testimonies have I taken, etc. The Scripture is called "testimonies" in respect to God himself, because it doth give a testimony to him, and makes God known to us: it gives a testimony of all those attributes that are himself, of his wisdom, of his power, of his justice, of his goodness, of his truth. The declaration of these, we have them all in the various books of the Scriptures: there is never a book, but there is a testification of these attributes. In the book of Genesis we have a testimony of his power in making the world, of his justice in drowning the world, and of his goodness in saving Noah. In the book of Exodus, we have a testimony of his providence in leading the people of Israel through the Red Sea, in bringing them out of Egypt; we have a testimony of his wisdom in giving them his law. What should I name more? In the New Testament, in the Gospel, all is testimony. As the Old gave testimony to God, so the New to Christ: "To him gave all the prophets witness"; not only the Old, but the New: "These are they that testify of me." Everywhere there is testimony of Christ, of his humility, in taking our nature; of his power, in working miracles; of his wisdom, in the parables that he spoke; of his patience and love, in the torments that he suffered for us. Both Law and Gospel the whole book of Scripture, and every part of it in these regards is fitly called "the testimonies of the Lord." And the holy Psalmist made choice of this name when he was to speak to the honour and glory of it; because it was that name from which he sucked a great deal of comfort, because it was the testimony of God's truth and goodness and wisdom and power to him; thereupon he makes so precious esteem of it as to account it his "heritage." Richard Holdsworth (1590-1649), in "The Valley of Vision."
