We attend the Feast of Tabernacles because we have been called out of this world, having been commissioned to be saints, separate from the world, holy and undefiled. Becoming holy is our full-time vocation as we live in the world. Unfortunately, Satan and the world have often established outposts or beachheads in our mind. As God's called out saints, we are commanded to extirpate those evil influences from our nervous system. In the World Tomorrow, we will have the opportunity to be kings and priests, instructing the new inhabitants on the ways of God. This position will be secure only if we have displaced the carnal pulls of this world with God's Holy Spirit.
