"The great people of the earth today are the people who pray! I do not mean those who talk about prayer; nor those who say they believe in prayer; nor those who explain prayer; but I mean those who actually take the time to pray. They have not time. It must be taken from something else. That something else is important, very important and pressing, but still, less important and pressing than prayer. There are people who put prayer first, and group the other items in life's schedule around and after prayer. These are the people today who are doing the most for God in winning souls, in solving problems, in awakening churches, in supplying both men and money for mission posts, in keeping fresh and strong their lives far off in sacrificial service on the foreign field, where the thickest fighting is going on, and in keeping the old earth sweet a little while longer." - S.D. Gordon
"Therefore, whether the desire for prayer is on you or not, get to your closet at the set time; shut yourself in with God; wait upon Him; seek His face; realize Him; pray." - R. F. Horton
"Time spent alone with God is not wasted. It changes us; it changes our surroundings; and every Christian who would live the life that counts, and who would have power for service must take time to pray." - M.E. Andross
Make time to pray. "The great freight and passenger trains are never too busy to stop for fuel. No matter how congested the yards may be, no matter how crowded the schedules are, no matter how many things demand the attention of the trainmen, those trains always stop for fuel." - M.E. Andross
"There is no other activity in life so important as that of prayer. Every other activity depends upon prayer for its best efficiency." - M.E. Andross
"…the man on his knees has leverage underneath the mountain which can cast it into the sea, if necessary, and can force all earth and heaven to recognize the power there is in 'His name.'" - M.E. Andross
When prayer has become secondary, or incidental, it has lost its power. Those who are conspicuously men of prayer are those who use prayer as they use food, or air, or light, or money." - M.E. Andross
"If the Christian does not allow prayer to drive sin out of his life, sin will drive prayer out of his life. Like light and darkness, the two cannot dwell together." - M.E. Andross
"We must begin to believe that God, in the mystery of prayer, has entrusted us with a force that can move the Heavenly world, and can bring its power down to earth." - Andrew Murray
"...[the] power of prayer can never be overrated. They who cannot serve God by preaching need not regret. If a man can but pray he can do anything. He who knows how to overcome with God in prayer has Heaven and earth at his disposal." - Charles H. Spurgeon
"Prayer is a spiritual law which cooperates with the mind of God. It has more in it than merely petition. It clothes itself in reality and power, with the force of God Himself. It is an attitude of spirit and mind. Language is secondary in true prayer." - Gossner.
"What the church needs today is not more machinery or better, not new organizations or more novel methods, but men whom the Holy Ghost can use— men of prayer, men mighty in prayer" - E.M. Bounds
"Prayer does not fit us for the greater work; prayer is the greater work." - Oswald Chambers.
"It is not enough to begin to pray, nor to pray aright; nor is it enough to continue for a time to pray; but we must patiently, believingly, continue in prayer until we obtain an answer" - George Müller
"Those persons who know the deep peace of God, the unfathomable peace that passeth all understanding, are always men and women of much prayer." - R. A. Torrey
"Prayer can never be in excess." - C. H. Spurgeon
