John knew that he was involved in a battle for truth. If false teachers successfully infiltrate the Church then the church would become indistinguishable from the world around her. That is precisely the tragedy we see happening in many churches today. John has already warned us about the conflict between light and darkness (1 John 1:1–2:6) and between love and hatred (1 John 2:7–17). Now He warns about a third conflict: the conflict between truth and error. Once again we see why it is so important for us to know the word of God. Last week we learned that God’s will is revealed to us in His word….KNOWING His Word will reveal His will and KNOWING His Word will expose false teachers.
