Psalms 30:5

The great things the Lord has done for us, both by his providence and by his grace, bind us in gratitude to do all we can to advance his kingdom among men, though the most we can do is but little. God's saints in heaven sing to him; why should not those on earth do the same? Not one of all God's perfections carries in it more terror to the wicked, or more comfort to the godly, than his holiness. It is a good sign that we are in some measure partakers of his holiness, if we can heartily rejoice at the remembrance of it. Our happiness is bound up in the Divine favour; if we have that, we have enough, whatever else we want; but as long as God's anger continues, so long the saints' weeping continues.

For his anger endureth but a moment. David here alludes to those dispensations of God's providence which are the chastisement ordered in his paternal government towards his erring children, such as the plague which fell upon Jerusalem for David's sins; these are but short judgments, and they are removed as soon as real penitence sues for pardon and presents the great and acceptable sacrifice. What a mercy is this, for if the Lord's wrath smoked for a long season, flesh would utterly fail before him. God puts up his rod with great readiness as soon as its work is done; he is slow to anger and swift to end it. If his temporary and fatherly anger be so severe that it has need be short, what must be the terror of eternal wrath exercised by the Judge towards his adversaries? In his favour is life. As soon as the Lord looked favourably upon David, the city lived, and the king's heart lived too. We die like withered flowers when the Lord frowns, but his sweet smile revives us as the dews refresh the field. His favour not only sweetens and cheers life, but it is life itself, the very essence of life. Who would know life, let him seek the favour of the Lord. Weeping may endure for a night; but nights are not for ever. Even in the dreary winter the day star lights his lamp. It seems fit that in our nights the dews of grief should fall. When the Bridegroom's absence makes it dark within, it is meet that the widowed soul should pine for a renewed sight of the Well beloved. But joy cometh in the morning. When the Sun of Righteousness comes, we wipe our eyes, and joy chases out intruding sorrow. Who would not be joyful that knows Jesus? The first beams of the morning brings us comfort when Jesus is the day dawn, and all believers know it to be so. Mourning only lasts to morning: when the night is gone the gloom shall vanish. This is adduced as a reason for saintly singing, and forcible reason it is; short nights and merry days call for the psaltery and harp.
