I guess I'm interested to know who tells you that you are not ready? Also, if I were you, I would ask that person(s) to clarify in what way(s) you are not ready, and if they are willing to help make you "ready." If they are not willing to help make you ready, then (as my mommy used to say, God rest her sweet soul) some-tin-wong. The first place I was on a team was a place where there was a pretty low glass ceiling. I would NEVER have had the opportunity to lead there, because the worship pastor would not have allowed it. If those in leadership aren't interested in raising up new leaders, and multiplying themselves, then I would look for another place to serve.
That being said, I'm assuming that you're sure of your call to ministry? If not, stop everything and start praying, and asking God to confirm it through the body.
