God is now testing and proving His people. Character is being developed. Angels are weighing moral worth, and keeping a faithful record of all the acts of the children of men. Among God's professed people are corrupt hearts; but they will be tested and proved. That God who reads the hearts of everyone, will bring to light hidden things of darkness where they are often least suspected, that stumbling blocks which have hindered the progress of truth may be removed, and God have a clean and holy people to declare His statutes and judgments. 1TT 109.1

Satan has controlled his mind, and he has done great injury to the cause of truth in northern Wisconsin. 1TT 109.3
