"Many do not recognize the fact as they ought, that Satan has got men fast asleep in sin and that it is his great device to keep them so. He does not care what we do if he can do that. We may sing songs about the sweet by and by, preach sermons and say prayers until doomsday, and he will never concern himself about us, if we don't wake anybody up. But if we awake the sleeping sinner he will gnash on us with his teeth. This is our work - to wake people up." (Catherine Booth)

"Beware in your prayers, above everything else, of limiting God, not only by unbelief, but by fancying that you know what He can do. Expect unexpected things, ‘above all that we ask or think’. Each time, before you Intercede, be quiet first, and worship God in His glory. Think of what He can do, and how He delights to hear the prayers of His redeemed people. Think of your place and privilege in Christ, and expect great things!" (Andrew Murray)

"Have you noticed how much praying for revival has been going on of late - and how little revival has resulted? I believe the problem is that we have been trying to substitute praying for obeying, and it simply will not work.  To pray for revival while ignoring the plain precept laid down in Scripture is to waste a lot of words and get nothing for our trouble. Prayer will become effective when we stop using it as a substitute for obedience." (A. W. Tozer)
