Verse 1-18 — The account the psalmist here gives of his troubles is very applicable to Christ: many hated him without a cause; nay, the Lord himself chastened him sorely, bruised him, and put him to grief, that by his stripes we might be healed. God is sometimes the strength of his people, when he is not their song; they have spiritual supports, though they want spiritual delights. Whether the believer traces back his comfort to the everlasting goodness and mercy of God, or whether he looks forward to the blessing secured to him, he will find abundant cause for joy and praise. Every answer to our prayers is an evidence that the Lord is on our side; and then we need not fear what man can do unto us; we should conscientiously do our duty to all, and trust in him alone to accept and bless us. Let us seek to live to declare the works of God, and to encourage others to serve him and trust in him. Such were the triumphs of the Son of David, in the assurance that the good pleasure of the Lord should prosper in his hand.
Verse 22,23, — , may refer to David's preferment; but principally to Christ. 1. His humiliation; he is the Stone which the builders refused: they would go on in their building without him. This proved the ruin of those who thus made light of him. Rejecters of Christ are rejected of God. 2. His exaltation; he is the chief Cornerstone in the foundation. He is the chief Top-stone, in whom the building is completed, who must, in all things, have the pre-eminence. Christ's name is Wonderful; and the redemption he wrought out is the most amazing of all God's wondrous works. We will rejoice and be glad in the Lord's day; not only that such a day is appointed, but in the occasion of it, Christ's becoming the Head. Sabbath days ought to be rejoicing days, then they are to us as the days of heaven. Let this Saviour be my Saviour, my Ruler. Let my soul prosper and be in health, in that peace and righteousness which his government brings. Let me have victory over the lusts that war against my soul; and let Divine grace subdue my heart. The duty which the Lord has made, brings light with it, true light. The duty this privilege calls for, is here set forth; the sacrifices we are to offer to God in gratitude for redeeming love, are ourselves; not to be slain upon the altar, but living sacrifices, to be bound to the altar; spiritual sacrifices of prayer and praise, in which our hearts must be engaged. The psalmist praises God, and calls upon all about him to give thanks to God for the glad tidings of great joy to all people, that there is a Redeemer, even Christ the Lord. In him the covenant of grace is made sure and everlasting.
