Charles H. Spurgeon on Psalms 107:2

Let the redeemed of the LORD say so. Whatever others may think or say, the redeemed have overwhelming reasons for declaring the goodness of the Lord. Theirs is a peculiar redemption, and for it they ought to render peculiar praise. The Redeemer is so glorious, the ransom price so immense, and the redemption so complete, that they are under sevenfold obligations to give thanks unto the Lord, and to exhort others to do so. Let them not only feel so but say so; let them both sing and bid their fellows sing. Whom he hath redeemed from the hand of the enemy. Snatched by superior power away from fierce oppressions, they are bound above all men to adore the Lord, their Liberator. Theirs is a divine redemption, "he hath redeemed" them, and no one else has done it. His own unaided arm has wrought out their deliverance. Should not emancipated slaves be grateful to the hand which set them free? What gratitude can suffice for a deliverance from the power of sin, death, and hell? In heaven itself there is no sweeter hymn than that whose burden is, "Thou hast redeemed us unto God by thy blood."
