"Times of revival are seasons in which many nominal and spiritually sleepy Christians, operating out of the semi-Pharisaism of religion, wake up to the wonder and ramifications of the gospel. Revivals are massive eruptions of new spiritual power in the church through a recovery of the gospel. In his sermon on Mark 9 Lloyd-Jones was calling the church to revival as its only hope. This is not a new program or something you can implement through a series of steps. It is a matter of wonder."
– Tim Keller in The Supremacy of Christ in a Postmodern World

“Repent therefore, and turn again, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord.” – Acts 3:19 (emphasis mine)
