Face it. In this entertainment-driven culture, even during worship, people are watching. And with the benefit of great media teams building great shots on screens of every size, they see your movements, your expressions, and they can sense whether there is anything genuine about your worship on the platform.
The key is to truly worship. Know the songs, practice the music, rehearse the vocals, and worship. You're not just a leader, you're a worship leader. And to lead, you have to go first.
