As a worship leader, I find this quite amusing. Before getting offended, realize that this is a video created by a church to point out our tendency to get caught up in our actions and forget about the one who is supposed to be receiving. We often worry so much about whether or not we are “appropriately” worshipping that we don’t truly worship.
The same can go for trying to sing along with songs you’ve never heard. Most of the time, it would be in your best interest to just think about God’s goodness and thank Him for His hand in your life than to attempt to sing a song you’ve never heard.
Watch this video with a sense of humor and see if any of these are things you find yourself concerned about when you should be focused on God.
