Psalm 108:1 O god, my heart is fixed; I will sing and give praise, even with my glory.… My heart is fixed; My heart is ready (Prayer-book Version); "My heart is steadfast" (Perowne). This psalm is clearly a compilation from two earlier psalms, and was probably arranged for liturgical worship. It represents the kind of experience which we properly associate with David. The references are such as suit his endeavor to extend and consolidate his kingdom; but the expression in ver. 11 suggests that the psalm was rewritten by a returned exile, to whom the Captivity was a "casting off" of the nation by God. What we now see is, that the mood of mind in which David first composed it is one eminently characteristic of him; and it is a mood eminently suitable for a restored exile, who was under the persuasion of the restoring mercies of God. What is the most striking thing in David's career is his fixity for God, the steadfastness of his purpose to live for God. He may have stumbled, made mistakes, acted unworthily, and openly sinned. And who, of woman born, has yet lived such a perfect life that he can venture to throw a stone at David? But from the beginning to the ending of his life David never heart swerved from God. "His heart was fixed." Fixed to trust; fixed to serve; fixed to praise. I. FIXITY IN PRINCIPLE IS THE SECRET OF FREEDOM. Illustrate by the tree, which is only free to spread and wave its branches, and put itself forth in flower and fruit, when the roots go well into the ground and hold firm. A man is not free who has no established principles, no fixed laws of conduct. He seems free, but really is a slave to his senses, and to all who have skill to offer sense-gratifications. True freedom is liberty to do right, and to do wrong, when a man is fixed that he will not do wrong. Sin enslaves those who are not fixed for God. II. FIXITY IN PURPOSE IS THE SECRET OF STRENGTH. Illust.: Joshua. "As for me and my house, we will serve the Lord." That resolve inspired a strong, unflagging life of service. Or take St. Paul. His resolve is, "To me to live is Christ;" so he exclaims, in conscious strength, "I can do all things through him that strengtheneth me." The man who knows what he means can gather up and unify his forces; hold them in restraint, and use them wisely. III. FIXITY IN HABIT IS THE SECRET OF DEFENCE. Here reference is to the habit of praise. This is the Christian's guard against depression and against temptation. What can the tempter do with a man whom he finds rejoicing in God? - R.T.
