Verse 1-5 — This psalm encourages to hope and trust in God; in his power and providence, and his gracious presence with his church in the worst of times. We may apply it to spiritual enemies, and the encouragement we have that, through Christ, we shall be conquerors over them. He is a Help, a present Help, a Help found, one whom we have found to be so; a Help at hand, one that is always near; we cannot desire a better, nor shall we ever find the like in any creature. Let those be troubled at the troubling of the waters, who build their confidence on a floating foundation; but let not those be alarmed who are led to the Rock, and there find firm footing. Here is joy to the church, even in sorrowful times. The river alludes to the graces and consolations of the Holy Spirit, which flow through every part of the church, and through God's sacred ordinances, gladdening the heart of every believer. It is promised that the church shall not be moved. If God be in our hearts, by his word dwelling richly in us, we shall be established, we shall be helped; let us trust and not be afraid.
Verse 6-11 — Come and see the effects of desolating judgments, and stand in awe of God. This shows the perfect security of the church, and is an assurance of lasting peace. Let us pray for the speedy approach of these glorious days, and in silent submission let us worship and trust in our almighty Sovereign. Let all believers triumph in this, that the Lord of hosts, the God of Jacob, has been, is, and will be with us; and will be our Refuge. Mark this, take the comfort, and say, If God be for us, who can be against us? With this, through life and in death, let us answer every fear.
