"Upon the progress of knowledge the whole progress of the human race is immediately dependent: he who retards that, hinders this also."

Satan cannot deny but that great wonders have been wrought by prayer. As the spirit of prayer goes up, so his kingdom goes down. Satan's strategems against prayer are three. First, if he can, he will keep thee from prayer. If that be not feasible, secondly, he will strive to interrupt thee in prayer. And, thirdly, if that plot takes not, he will labour to hinder the success of thy prayer.
