Psalms 107:1

Here is, I. A general call to all to give thanks to God, Psa 107:1. Let all that sing this psalm, or pray over it, set themselves herein to give thanks to the Lord; and those that have not any special matter for praise may furnish themselves with matter enough from God's universal goodness. In the fountain he is good; in the streams his mercy endures for ever and never fails. II. A particular demand hereof from the redeemed of the Lord, which may well be applied spiritually to those that have an interest in the great Redeemer and are saved by him from sin and hell. They have, of all people, most reason to say that God is good, and his mercy everlasting; these are the children of God that were scattered abroad, whom Christ died to gather together in one, out of all lands, Joh 11:52; Mat 24:31. But it seems here to be meant of a temporal deliverance, wrought for them when in their distress they cried unto the Lord, Psa 107:6. Is any afflicted? Let him pray. Does any pray? God will certainly hear and help. When troubles become extreme that is man's time to cry; those who but whispered prayer before then cry aloud, and then it is God's time to succour. In the mount he will be seen. 1.
