I consider true revival of the church when historically the Church deepened their spiritual knowledge by discussion of doctrine or even wrestled with issues involving doctrine. That may on the surface sound very cold as we are often warned by dire evangelists that we "have to believe in our hearts and not our heads" and the undo emphasis in some sort of spiritual manifestations.However, without knowledge, it acts as a ship or airplane without a rudder and will go spiraling out of control. What evangelists should be saying (but often do not come across as saying) is that true faith is not merely the mental assenting of facts only, but a personal application and action on the promises of God. Faith in the New Testament is really more of a verb (an action) than a noun (a belief) that modern day people confuse it with. In fact, what I just said is a word of knowledge that can make the difference between saving faith and mere acknowledgment. Then..... if we continue looking deeper into spiritual truths based on history, prophecy, and spiritual principles, we can get the full appreciation of God's entire truth.Thus, revival will come as our emotions follow the spiritual learning of the bible and praise will result. However, if we pray for a revival and it ends up with someone jumping up and down praising the Lord, and then ask that person, "What did you learn today that made you alive?" If the answer is "I don't know, but it sure felt good!" Then I know that's the wrong kind of "revival". In other words, make sure that if one means by revival "being on fire for the Lord" that it has a strong rock foundation in the knowledge of His word. When some Christians see a deeper meaning to something, often it is considered fringe by others. But I'll tell you, there is nothing more revitalizing than discovering a hidden truth that seems new because one just learned it. And one just naturally wants to praise the Lord for it. That's true revival.
