Jesus Christ makes clear that he sowed the world with good seed, and the Devil came by night and sowed the world with evil seed. He decided to let both grow together until the harvest when his angels will separate the two! We have this exact situation in our world, good vs. evil, in every area of life.
It really is NOT left vs. right, black vs. white, male vs. female, it is always good vs. evil. But evil workers try to twist things around so as to call things black vs. white, etc. We must not fall for this deception.
