Jesus Christ, our LORD and Savior did it.
Moses, Esther and Ezra did it.
David, Daniel, Isaiah and Nehemiah did it. 
John the Baptist and his disciples did it. 
Peter, Paul and all the Apostles did it. 
Jesus Christ fasted for forty days and forty nights, as did Moses and Elijah.

Fasting is a guaranteed method of advancing your spiritual maturity and development.

Fasting: it's not for everybody, but it might be for you!

Why don't you try it and see?

GOD the Father suggests it!
GOD the Son expects it!
GOD the Holy Spirit empowers it!
