Let the world know what you live for...not what you fall for!
The cross has two sides to it. One side is what Jesus did for us. He forgave us our sins. The other is the God side. God now lives in man!
Jesus did not command us to "develop" leaders. He commanded us to make "disciples". The world "develops" leaders, the Church "disciples" them. The two are not the same.
Belief has the power to change your inner state and your outer world.
