That they might set their hope in God,.... And not in the creature, nor in any creature enjoyment; see Job 31:24, the Lord is the only proper object of hope and confidence; Christ, who is truly God, is the hope of his people, and in him they place it, as they have great reason to do; since with him there is mercy, the mercy of God is proclaimed in him; and with him there is redemption, which includes the blessings of peace, pardon, and righteousness; and a plenteous one, a redemption from all sin; and it is the Gospel which points out these things in Christ, and encourages a firm and settled hope and trust in him: and this shows that that is meant by the law and testimony; since the law of Moses gives no encouragement to hope in God; it convinces of sin, but does not direct to a Saviour, and so leaves without hope; it works wrath, terror, and despair; it is in the Gospel only Christ is set before men, as the object of hope to lay hold on, and which is as an anchor sure and steadfast, where they may securely place it: and not forget the works of God; which the Gospel declares; not only the miracles of Christ recorded by the evangelists, but the works of grace, redemption, and salvation; the remembrance of which is kept up by the ministry of the word, and the administration of ordinances: but keep his commandments; the commandments of Christ, and which are peculiar to the Gospel dispensation; and are to be kept in faith, from a principle of love, through the grace and strength of Christ, and to the glory of God by him; see Joh 14:15.
