12 “I have many more things to say to you, but you cannot bear them now.13 But when He, (R)the Spirit of truth, comes, He will (S)guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. 14 He will (T)glorify Me, for He will take of Mine and will disclose it to you. 15 (U)All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose it to you.” – John 16:12-15 (NASB)
The Holy Spirit is a Christian’s personal guide in regard to the specific will of God in that individual’s life. He speaks to the Christian on behalf of God, so there is no reason to doubt or fear his message. His sole purpose is to glorify God the Father and God the Son, at all times.
Learning to discern, interpret, and implement the wishes of the Holy Spirit is crucial for any follower of Christ to be effective in his discipleship.
