Psalms 147:13

The church, like Jerusalem of old, built up and preserved by the wisdom, power, and goodness of God, is exhorted to praise him for all the benefits and blessings vouchsafed to her; and these are represented by his favours in the course of nature. The thawing word may represent the gospel of Christ, and the thawing wind the Spirit of Christ; for the Spirit is compared to the wind, Joh 3:8. Converting grace softens the heart that was hard frozen, and melts it into tears of repentance, and makes good reflections to flow, which before were chilled and stopped up. The change which the thaw makes is very evident, yet how it is done no one can say. Such is the change wrought in the conversion of a soul, when God's word and Spirit are sent to melt it and restore it to itself.

For he hath strengthened the bars of thy gates. Her fortifications were finished, even to the fastenings of the gates, and God had made all sound and strong, even to her bolts and bars: thus her security against invading foes was guaranteed. This is no small mercy. Oh, that our churches were thus preserved from all false doctrine and unholy living! This must be the Lord's doing; and where he has wrought it his name is greatly to be praised. Modern libertines would tear down all gates and abolish all bars; but so do not we, because of the fear of the Lord. He hath blessed thy children within thee. Internal happiness is as truly the Lord's gift as external security. When the Lord blesses "thy sons in the midst of thee", thou art, O Zion, filled with a happy, united, zealous, prosperous, holy people, who dwell in communion with God, and enter into the joy of their Lord. When God makes thy walls salvation thy gates must be praise. It would little avail to fortify a wretched, starving city; but when the walls are strengthened, it is a still greater joy to see that the inhabitants are blessed with all good gifts. How much our churches need a present and abiding benediction.
