Revivals usually have a strong leader as a central figure. Revivals usually center on a person, often a charismatic individual, who has, or is seen to have, power. Even Joash's revival fits the pattern, for although he was himself led by others, the nation as a whole saw him as a leader. In Jerusalem there were 12 apostles, but it was Peter's shadow that people wanted to fall on them. Thus, if God sends revival, strong leaders will likely emerge even in groups that want to discourage such charismatic figures.
Revivals often have a strong biblical base.
Whether it was the case of a prophet pointing people back to the ancient traditions, Josiah discovering anew the law, or Peter proclaiming the relationship of the Old Testament to the life and death of Jesus, revival is normally based on the Bible and rooted in a new appreciation of the biblical text. Revival phenomena will not likely produce lasting good unless they drive people to a deeper study of the Scripture resulting in a more devoted living of Scripture. Revivals' effects depend upon what happens to the majority of the people. When large numbers of people change their lives, revival lasts. If people only change while around the revival leaders or while the influence of these leaders is felt, then it is unlikely that the revival will produce lasting good.
