Prayer is the mightiest weapon that God has placed in our hands. It is the best weapon to use in every difficulty, and the surest remedy in every trouble. It is the key that unlocks the treasury of promises, and the hand that draws forth grace and help in time of need. It is the silver trumpet that God commands us to sound in all our necessity; it is the cry He has promised always to listen to.

~ J. C. Ryle (1816-1900)
