Mathew 10:8

Heal the sick, cleanse the lepers, raise the dead, cast out demons.  Freely you have received, freely give.

Jesus came to this earth to demonstrate the power of God working through man. A time is coming when the Church will need to operate in the power that Jesus demonstrated to us before He left. We need to develop our faith and have the God kind of faith powered by love to reach the lost. God gave to us freely, and so we should freely give.
