In between Colossians and 1 Thessalonians we read three Psalms and one chapter of Isaiah.
Psalm 86, a Prayer of David. A plea for help, David pours out his needs and confesses his total dependence on God to teach him His ways.
Psalm 87, of the Sons of Korah. A song of praise to Zion, the City of God and its citizens, even to those gentiles so honored.
Psalm 88, of the Sons of Korah, Heman the Ezrahite. This may be the saddest Psalm of them all, seemingly without hope, and yet?
Isaiah 40. After reading Psalm 88 we need something uplifting, and this chapter has helped me immensely. I will not comment any further. Read it, listen to the music, read it again and let it sink in!
