SomeTimes we get comfortable doing the same things or being in the same place.Many Christians told God to use them or I will go send me. When the  time comes  to be used or go, we don't want to or pray we don't have to. I am guillty because I was thinking I would be unconfortable. Yet when I obey God's call to be used or go where he was sending me it wasn't as bad as I thought it would be. God is looking for those he can use and will go no matter what or how they feel.
