Purity of mind, heart, conscience, and soul is a major part of being a child of God. The word means "clean" and we are very attentive to cleanliness when it comes to food or drink. We want what we take into our body to be pure, but it seems that we are very careless about what enters into our mind, our heart, and our soul. The devil is on the rampage right now like most of us have never seen. Sin, worldliness, and immorality are commonly reported among the churches. When sickness and disease start spreading we began an urgent search for the cause, and the cause is always pollution, contamination, something corrupt that has invaded our food, drink, or home. The people of God need to do the same immediately.
