I think there are a lot of people that lead worship don't really understand the weight of what they do. But I think it is all about leadership. It's how you lead people into understanding what this is about. But also the wind of God, the fresh Spirit of God has been amazing, and that is what has caused people to turn their hearts towards it. Worship music is the most popular thing in Christian music.
In my experience, professionals who are best in any field approach their work with humility. They know that their work is more than just a job. It's an exploration of life. Even on days when they feel most confident, things can go wrong. Sometimes even the good things that happen are a mystery - a surprise. There are always elements outside our control. That's humbling - or should be.
