False Ideas of Sanctification^{*1862, Testimonies for the Church 1:332-340 (Northern Wisconsin).}

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

The Captain of our salvation leads His people on step by step, purifying and fitting them for translation, and leaving in the rear those who are disposed to draw off from the body, who are not willing to be led, and are satisfied with their own righteousness. “If therefore the light that is in thee be darkness, how great is that darkness!” Matthew 6:23. No greater delusion can deceive the human mind than that which leads men to indulge a self-confident spirit, to believe that they are right and in the light, when they are drawing away from God's people, and their cherished light is darkness. ...1TT 109.2

Brother J received from Elder K a false theory of sanctification, which is outside of the third angel's message, and wherever received destroys the love for the message. I was shown that Elder K was upon dangerous ground. He is not in union with the third angel. He once enjoyed the blessing of God, but does not now, for he has not prized and cherished the light of truth which has shone upon his pathway. He has brought along with him a theory of Methodist sanctification, and presents that in front, making it of the highest importance. And the sacred truths applicable to this time are by him made of little consequence. He has followed his own light, and been growing darker and darker, and going further and further from the truth, until it has but little influence upon him. Satan has controlled his mind, and he has done great injury to the cause of truth in northern Wisconsin.1TT 109.3
