The nay-sayers who have never tried this will insist that it will not work. It will not work for them because they have never tried it and relied on the power of Scripture and the Holy Spirit. We have current proof that it works. God is moving in certain parts of the world through this principle. What we have seen has totally convinced us of the truth of God’s Word and we will follow this principle as long as God gives us breath.
