The Holy Spirit

AND JESUS SAID

When the Spirit of truth comes, he will guide you into all truth. He will not be presenting his own ideas; he will be telling you what he has heard. He will tell you about the future. He will bring me glory by revealing to you whatever he receives from me. All that the Father has is mine; this is what I mean when I say that the Spirit will reveal to you whatever he receives from me.”  John 16:13-15

The truth into which the Holy Spirit guides us is the truth about Christ. The Spirit also helps us to discern right from wrong through patient practice.
