When men and women fall under the corrupting power of Satan, it is almost impossible to recover them out of the horrible snare so that they will ever again have pure thoughts and clear conceptions of God's requirements. Sin, to their deluded minds, has been sanctified by the minister, and it is never again regarded in the loathsome light that God looks upon it. After the moral standard has been lowered in the minds of men, their judgment becomes perverted, and they look upon sin as righteousness, and righteousness as sin. By associating with these, whose inclinations and habits are not elevated and pure, others become like them. Their tastes and principles are almost unconsciously adopted. 2TT 35.1
If the society of a man of impure mind and licentious habits is chosen in preference to that of the virtuous and pure, it is a sure indication that the tastes and inclinations harmonize, that a low level of morals is reached. This level is called by these deceived, infatuated souls, a high and holy affinity of spirit—a spiritual harmony. But the apostle terms it “spiritual wickedness in high places” (Ephesians 6:12), against which we are to institute a vigorous warfare. 2TT 35.2
When the deceiver commences his work of deception, he frequently finds dissimilarity of tastes and habits; but by great pretensions to godliness he gains the confidence, and when this is done, his wily, deceptive power is exercised in his own way to carry out his devices. By associating with this dangerous element, women become accustomed to breathe the atmosphere of impurity and almost insensibly become permeated with the same spirit. Their identity is lost; they become the shadow of their seducer. 2TT 35.3
Men professing to have new light, claiming to be reformers, will have great influence over a certain class who are convinced of the heresies that exist in the present age and who are not satisfied with the spiritual condition of the churches. With true, honest hearts, these desire to see a change for the better, a coming up to a higher standard. If the faithful servants of Christ would present the truth, pure and unadulterated, to this class, they would accept it, and purify themselves by obeying it. But Satan, ever vigilant, sets upon the track of these inquiring souls. Someone making high profession as a reformer comes to them, as Satan came to Christ disguised as an angel of light, and draws them still further from the path of right. 2TT 35.4
The unhappiness and degradation that follow in the train of licentiousness cannot be estimated. The world is defiled under its inhabitants. They have nearly filled up the measure of their iniquity; but that which will bring the heaviest retribution is the practice of iniquity under the cloak of godliness. The Redeemer of the world never spurned true repentance, however great the guilt; but He hurls burning denunciations against Pharisees and hypocrites. There is more hope for the open sinner than for this class. ... 2TT 36.1
