David was a worshipper {psalm 34:1)! He was skillful in playing a musical instrument – the harp (1 samuel 16:18). He even became a deliverance minister to king saul using praise and worship to cast away demons (1 samuel 16:23). He worshipped God with all that was within him (psalm 103:1). All that is within includes lungs, intestine, liver, colon, etc. He therefore danced lavishly before the Lord (2 Samuel 6:4-16). He appreciated that he heights he achieved in life were not a result of his ability or expertise but gave all the glory to God (2 Samuel 7:18; 1 Chronicles 17:16)
