Acts 1:8
But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.

I would rather win souls than be the greatest king or emperor on earth; I would rather win souls than be the greatest general that ever commanded an army; I would rather win souls than be the greatest poet, or novelist, or literary man who ever walked this earth. My one ambition in life is to win as many as possible.
