Taint of Spiritual Malaria—The Lord calls upon you, my brother, to step down from the work, leave the walls of Zion, or be a converted man. When your own heart is sanctified through the truth, there will be in it no moral defilement. It will now require a most desperate resistance to unholy suggestions upon your part, because your soul is tainted with spiritual malaria. You have breathed a satanic atmosphere. You have not been a man in the sight of God. When your mind should have been growing, your ideas elevated, and your plans and labors broadened, you have been growing less and less efficient as a worker, because God is not blessing your efforts.
