Jn.16:13 – But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own, but whatever He hears, He will speak; and He will disclose to you what is to come.
When someone comes to Christ his whole means of learning is radically changed. The change is connected to the source of the teaching. Rather than being dependent on our own intellect, the talent and diligence of our teachers, and our own hard work, we become dependent on the Holy Spirit as our Teacher. Jesus said that He alone would “lead us into all truth”. The Holy Spirit leads us to truth Himself, Jesus is the word or the truth of God expressed in a man. Our part is to search the scripture, His part is to give us divine illumination of the word. Christ is literally in every part of the Bible, the Holy Spirit unlocks this for us. Here is how Barclay describes the Holy Spirit as our teacher.
“Revelation is the taking of the things of Jesus and revealing their significance to us. Part of the greatness of Jesus is his inexhaustibleness. No one has ever grasped all that he came to say. No one has fully worked out all the significance of his teaching for life and for belief, for the individual and for the world, for society and for the nation. Revelation is a continual opening out of the meaning of Jesus. There we have the crux of the matter. Revelation comes to us, not from any book or creed, but from a living person. The nearer we live to Jesus, the better we will know him. The more we become like him, the more he will be able to tell us. To enjoy his revelation, we must accept his mastery.”
The Holy Spirit reveals the amazing mystery of God revealed in a man. He unveils the mystery of the virgin birth, the amazing humility seen in Christ’s manhood, the power of His miracles, redemption seen at Calvary, the power of the resurrection, and the amazing nature of His heavenly ministry. He will lead us into all truth; that is a mouthful!
So each one of us have a personal teacher. This is better than a private tutor, He is there with us constantly. He not only has all of the information and wisdom at His disposal, He is the source of all wisdom being wisdom Himself.
