Read 1 John 4:1-6

But you belong to God, my dear children. You have already won a victory over those people, because the Spirit who lives in you is greater than the spirit who lives in the world. - 1 John 4:4 (NLT)

The evil one is defeated, but still active in our present world. We should be aware of this, and guard our hearts and minds against false doctrine, but we need not fear, for the victory is already won. By continuing to search the Scriptures, and by daily remaining in fellowship with God, we can discern God’s truth and know what is of God and what is not.
