How untiringly God has kept guard over His church! Shall we not act our part that He may give us the grace that will enable us to attain to perfection of Christian character? Do not allow yourself to be led to think that you will live in heaven while in this fallen world. Those who think this keep their minds on the strain for some wonderful experience that will waft their souls into a refined, spiritual atmosphere. But this is not the true science of Christian experience. When they suppose they have reached spiritual heights of refinement, Satan, in the garb of an angel of light, presents to them indulgences in which he makes it appear there is no sin. MM 101.3
I would warn you against these apparently refined doctrines, which say that sin is not sin, and teach the possibility of living a spiritualistic life above the grossness of sin. I write this because there are minds entering into temptation in regard to this refined science of spiritualistic attainments. You will meet this science, and you will hardly know how to handle it. MM 101.4
We have reached the perils of the last days, when some, yes, many, shall depart from the faith, giving heed to seducing spirits and doctrines of devils. Be cautious in regard to what you read and how you hear. Take not a particle of interest in spiritualistic theories. Satan is waiting to steal a march upon everyone who allows himself to be deceived by his hypnotism. He begins to exert his power over them just as soon as they begin to investigate his theories.—Letter 123, 1904. MM 101.5
