Is It Proper to Preach the Psalms?

To be honest, I have always assumed that the Psalms could and should be preached. But as Sidney Greidanus points out, Claus Westermann, Donald Gowan, and others believe that the Psalms can be prayed and sung but they should not be preached. but Greidanus offers four reasons why the Psalms should be preached.

1. "The editors of the Psalter have placed Psalm 1, a torah (wisdom) psalm, at the head of this collection in order to signal that every following psalm is to be read as part of God's torah, teaching, instruction for Israe1."
2. "Though many psalms originated as a human word to God, every psalm is now part of the Psalter and was accepted in the Canon as God's word for Israel."
3. "The New Testament authors accepted the Psalter not just as Israel's word to God but as God's word to his people"
4. "Jesus not only prayed the psalms but used them, more than any other Old Testament book, for his preaching and teaching."
