The bible say when praise goes up his blessings comes down..
As Christians our Mouth and Hands is all that is need to Praise God..
Ezekiel 25:6 "For thus saith the Lord God; Because thou hast clapped thine hands, and stamped with the feet, and rejoiced in heart with all thy despite d against the land of Israel; [7] Behold, therefore I will stretch out mine hand upon thee, and will deliver thee for a spoil to the heathen;"
Praising God is way of saying thank you too
