Pervert the Gospel

Gal1:6-7 Paul instructed the church not to pervert the gospel and any man or angel if they preach another gospel let them be accursed.
Through the spirit of God Tr.Fuorr expounds on how many ministers have perverted the gospel by using mediums like anointing oil, the mantle and other mediums for ministering the gospel, they claim it is the power of God, the spirit of God.
By the spirit He instructs the saints to minister the gospel and not mediums because we should walk by faith not by mediums.
