We can't create a revival. We can't organize a revival. But we can agonize in prayer for a revival. A revival is a supernatural invasion of God. It is something that God does for us and not something we do for Him. One person defined revival as a community saturated with God. Richard Owen Roberts, who wrote a great book called Revival, described it as "an extraordinary movement of the Holy Spirit producing extraordinary results." A.W. Tozer defined revival as that which changes the moral climate of the community. Revival is nothing more or less than a new beginning of obedience to God. Nonbelievers don't need revival; they need salvation. The church needs revival. Revival is for believers only, but evangelism is for nonbelievers. Charles Spurgeon said, "To be revived is a blessing which can only be enjoyed by those who have some degree of life. Those who have no spiritual life are not, and cannot be, in the strictest sense of the term, subjects of a revival. A true revival is to be looked for in the Church of God."
