Pondering the weapon of praise

Been watering the word with thanksgiving: "Thank you lord that by Jesus' wounds Gabe and I were healed." But am pondering giving the lord showers of praise. I've seen praise do wonders. In the physical realm. But not lately. Of course, St Paul says it's not as if we are beating against the air. So I know that in the spiritual realm we're battling spiritual wickedness in high places. But I'd like to see a manifestation in our life. Expect great things.
