2 Samuel 6:22a shows us a king who is not ashamed to worship God with his whole heart. "I will become even more undignified than this..."(NIV). He didn't care what people said or thought about him dancing before the Lord with all his might.
So, why is it exactly that we care what others think or say? Why are we more concerned with how people see us rather than how God sees us? Why do we let people determine how we worship and praise our God? Somewhere along the way, "religion" got in the way of WORSHIP. I encourage you to allow the Spirit of God to take control, and stop being afraid of men and their faces.
The very next opportunity you have to praise and worship God in public, I dare you to just let loose, let the make-up run, let the heel break on that shoe, let the hairpins fly! He is worthy of all that and much more. Will you become undignified for His glory today? Think about it.
