I believe that the key to revival is the Lord giving the gifts of the Holy Spirit, to increase the fruits of the Holy Spirit.
Besides the baptism in the Holy Spirit, a Spirit-filled church leader needs to have balance and maturity; that is what is needed to properly supervise the operation of the gifts of the Holy Spirit.
Some call it apostolic and prophetic ministry, some don't, I don't like to get hung up on labels.
Half of the gifts of the Holy Spirit have to do with hearing from the Lord. I believe that the bible is the definitive word of God; but that the rhema (currently spoken) word of the Lord is something that is very important also. And just to mention 'logos' being the written word of the Lord (the bible).
