Psalm 30 is a psalm of praise for the way God had delivered and healed David (vv. 1-3, 9-11). But as commentators Jacobson and Tanner put it, the psalm isn’t just a psalm of praise, but “a psalm about praise” calling hearers to “a complete life of praise.” It’s God’s merciful and restoring character that gives His people reason to live a life of praise (vv. 4-5). To be abandoned by God would be to be “silenced” (v. 9). But because God turns “wailing into dancing” (v. 11), we have reason to “praise [Him] forever” (v. 12). As we praise Him, God can fill our hearts with rhythms of joy and give us hope for the days ahead.
