I’ve been reading E.M. Bounds, The Necessity of Prayer. What a mind and heart this man had for God - and for prayer! Bounds writes in the first chapter,

If Jesus dwells at the fountain of my life; if the currents of this life have displaced and superceded all self-currents; if implicit obedience to him is the inspiration and force of every movement of my life, then he can safely commit the praying to my will, and pledge himself, by an obligation as profound as his own nature, that whatsoever is asked shall be granted. Nothing can be clearer, more distinct, more unlimited both in application and extent, than the exhortation and urgency of Christ, “Have faith in God.”

You see faith is the indispensable means to cultivating the kind of life Bounds talks about in the opening of the paragraph. It is the heart of prayer. And which Christian among us doesn’t long for that kind of life?

John 15:7, If you abide in me, and my words abide in you, ask whatever you wish, and it will be done for you.
