What does the Bible say about the Spirit of God?

The Spirit of God plays a crucial role in distinguishing truth from error among the various religious teachings in the world. As stated in 1 John 4:1, believers are urged not to believe every spirit, but to test the spirits to see if they are from God. The distinguishing mark of the Spirit of God is the confession that Jesus Christ has come in the flesh. This confession affirms both the incarnation and the redemptive work of Christ, emphasizing His divinity and humanity. Through this lens, we can assess teachings and teachers to discern whether they align with God's truth.
