Ministries are birthed through prayer, are sustained by prayer and fail for lack of prayer. 

These words came to me many years ago as I was praying. I believe they are profound for two very simple reasons. First, it was God, in the person of the Holy Spirit, who spoke them to me. Second, when they are applied, they can be life changing.

The most compelling reason I can think of to pray is because Jesus did! If God in the flesh, the Redeemer of mankind prayed, shouldn't we? The question is rhetoric, the answer is a resounding, yes, of course we should pray!
