Here is a hymn I wrote based on 2 Chronicles 20. Stanza 1 relates how King Jehoshaphat reminds
the Lord about what he, mighty God, had all done for his people in the
past. In stanza 2 the king prays about how Judah was being oppressed by
enemy hordes. In the first part of stanza 3 the LORD declares that the
battle is his, not the people's; in the second half God's people
resoundingly praise the LORD.
Here's a link to the rest of my songs.
