Psalm 9
Amos 1:3-2:16 has focused a lot on God’s judgment of the nations and his perfect justice. Psalm 9 would be an ideal song to sing together with your sermon. You can sing Psalm 9:1-10 as a song of praise at the start of your worship service and then sing Psalm 9:11-20 after the conclusion of your sermon.
