The book of Psalms is biblical poetry of worship, praise and prayers. The Psalms have four major themes: psalm telling us about those who are blessed, psalms expressing the emotions we feel, psalms of worship, and psalms of prophecy of the coming Messiah. The best-known psalm, and most beautiful description of the relationship between God and man, is Psalm 23. This blessed man psalm portrays God as a wise and gentle shepherd.
