Roy Hessian says in his book The Calvary Road:
“The outward forms of revivals do, of course, differ considerably but the inward and permanent content of them all is always the same – a new experience of conviction of sin among the saints; a new vision of the cross of Jesus and of redemption; a new willingness on man’s part brokenness, repentance, confession and restitution; a joyful experience of the power of the blood of Jesus to cleanse fully from sin and restore and heal all that sin has lost and broken; a new entering into the fullness of the Holy Spirit and of His power to do his own work through His people; and a new gathering in of the lost ones to Jesus.”
Revival is taking place in pockets all over the world and each one is different in how it starts, how God’s touch fall, how many are saved and complete in Him, country, people group. There are so many variations of the same thing, but a true revival or renewal will see many or all of the content that Roy Hessian talks about. It is the same God and same Spirit that fell on Abraham, on John the Baptist, on Elijah, on Jesus at His baptism, through Jesus on the cross. He never changes, and salvation and reconcilliation will always come through Christ and His saving blood.
