In 1 John 4:1-6 the apostle John warns the leaders of the church not to believe every “spirit” that comes into their community claiming to hear from God. For many “false prophets” are in the world. By looking back to chapter one, we re-examine what is the context of this letter and how it’s related to the warning in chapter four specifically relating to those who are denying the incarnation of Jesus. Why is the apostle so vigilant about fighting for this tenet of the faith? Because believing God came in the flesh is not just a doctrine that defines what Christians ought to believe, but it’s essential to who we are and how we are able to relate to God today. We also examine what it means to us that “he who is in us is greater than than he who is in the world.” While we are to watch out for the enemy’s schemes, we need not fear him.
