There are much more heresies that I did not indicate. When a JW comes to your door, we as Christians are to give them the Gospel of Jesus Christ. Even though they are persistent, we as Christians still need to remember they are lost, souls. They are also made in the image of God, so please be respectful but direct at the same time.
