If you are reading with these Psalms in their historical context you know that this is based on David’s activity in 1 Samuel 21. David fled to Gath and pretended to be a mad man in order to protect himself because in the ancient world insane people were not harmed in order not to provoke the gods.
David celebrated God's graciousness to him in the midst of his trials. Then he exhorted others to come praise Him.
When is the last time you actually praised God? Outside of our church and maybe a Bible study, most of us do not take the time to praise Him. What a challenge for me to hear that David did it continually (Psalm 34:1).
I have made a commitment to take a "praise walk" around the block. What will be your "I will" statement in response to this Psalm?
I also find the book Face to Face: Praying the Scriptures for Intimate Worship by Kenneth Boa helps me as all the prayers start out in adoration.
Take time out of your busy day today to praise God!
Pray responsively through Psalm 34. Nothing teaches us to praise God like the Psalms!
