You teach what you know, but you reproduce what you are.
You focus on the depth of your relationship [with God]; let Him determine the scope of your ministry
So the first reason for studying Scripture is that it is a means of spiritual growth. There is none apart from the Word. It is God's primary tool to develop you as an individual.
Vision without integrity is not mission - it's manipulation.
Jesus never discipled one-on-one.
God is not looking for more stars; He's looking for more servants.
