God has been looking for people who will say yes and then step out and do. I know that there are people out there because in ministering to people I hear the same thing over and over again, "I don't know what my calling is" or "God has not called me to do this or that". So, I know that he is calling! The bible makes it clear when it says, "Go and preach the gospel, or Go and make disciples. That sure sounds like a call to me.
Any way, God is calling and we need to be listening. We need to answer that call and our lives will never be the same again.
