O prayer! Prayer! It brings and keeps God and man together. It raises man up to God and brings God down to man. If you would keep your walk up with God, pray, pray without ceasing.
— George Whitefield
All who call on God in true faith, earnestly from the heart, will certainly be heard, and will receive what they have asked and desired, although not in the hour or in the measure, or the very thing which they ask; yet they will obtain something greater and more glorious than they had dared to ask.
— Martin Luther
