 That kind of singing, those shouts of joy, that kind of singing flows out of hearts that have been revived. The repentance, the grieving, the mourning, the sorrow over sin now gives way to singing. It's the song of the heart set free. And that's a characteristic of revival, as we said a few moments ago. In revival, you'll often have people who sing the same songs that they've been singing in church for years. But it's a new song.
