Purity and pollution both affect the way we view the world around us. To the pure all things are pure. He looks for the good, finds it, and rejoices in it. Them that are unbelieving and defiled in their mind and conscience only look for the bad and find it in everything and everyone. Rotten fruit is sweet to a worm but noxious to normal people. These are the two kinds of people in this world. When we find ourselves thinking that there is nothing but evil and no good in this world we are under the influence of the devil, because that is a lie. No true Christian can live with such an attitude and disposition.
