During the rise of the third angels message, slander has been common. Some will resort to slander when their arguments cannot be proven from the scriptures.
The Seed of Criticism
“Every deed of thoughtful kindness, of obedience, or of self-denial, will reproduce itself in others, and through them in still others. So every act of envy, malice, or dissention is a seed that will spring up in a ‘root of bitterness’ (Hebrews 12:15), whereby many shall be defiled. And how much larger number will the ‘many’ poison? Thus the sowing of good and evil goes on for time and for eternity.”
