"So how is God glorified by prayer? Prayer is the open admission that without Christ we can do nothing. And prayer is the turning away from ourselves to God in the confidence that He will provide the help we need. Prayer humbles us as needy and exalts God as all-sufficient." --John Piper
"We should waste no time in getting down on our knees in prayer in order to release pent-up, divine blessing on multitudes in the devil's clutches. Where you have people actually praying for the lost, you find the lost being saved." --Douglas F. Kelly
"It is, therefore, necessary for the Spirit of God to burn into our hearts this mystery, that the most important work we have to do is that which must be done on our knees, alone with God, away from the bustle of the world and the plaudits of men... If the labor of prayer does not precede, as well as accompany, all of our work in the kingdom, it will become nothing but a work of man, more or less capably done and with more or less effort and agitation as the case may be, but resulting in nothing but weariness both to ourselves and to others." --O. Hallesby
