The slumbering church begins to awaken from its sleep. Sins are confessed. Repentance grips the hearts of God's people, and a passion for a lost world starts to overwhelm those who have experienced Christ's forgiveness. The bottom line is that multitudes are born into the kingdom of God. This pattern has been a historic one that has been repeated over and over again.
Prayer is always the initiator of great revivals.
It's the expression of humble hearts. Without You, I can do nothing. It's absolute dependence upon God. Revival is the manifest grace of God upon His people. That grace is always released in the humble heart.
