Read Matt. Chapter 13, the parable of the wheat and tares. Let both grow together until the harvest. The harvest is the end of the world. At the time of the harvest, he will send forth his angels and gather together first the tares, not the wheat. Bind the tares in bundles to be burned, and gather the wheat into my barn. Also, behold he cometh with clouds and every eye shall see him, even the eyes of those that pierced him.
