It's very simple :wink: , pray about it and ask god if this is what He wants you to do. And by all means, don't try to step ahead of God before he gives you an answer to go or not to go, cuz' you'll find yourself in a LOT of trouble, trust me 8O .
Also man, do not let the popularity, media, or SIZE and MEMBERSHIP of the church be a factor at all; Iv'e seen a lot of musicians do so, and find themselves in a heck of a lot of trouble.
Be steadfast and unmovealble, and wait on the lord because what God has for you is for you :wink:
