But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
The spoken words of Christ are spirit and life. They never die, cease or be dormant. The Holy Spirit is preserving them throughout the past generations to fulfill his given task to bring back to our remembrance the things Jesus have told His disciples. The Holy Spirit is the link to knowing what Jesus was trying to relay to His followers. Those unknown people in the past who lived, heard and remembered the sayings of Christ in their hearts and minds were inspired by the Holy Spirit to become reliable witnesses of the gospel of Christ.
How can we be sure that the words of Christ recorded by Matthew, Mark, Luke and John were actually His? The simple answer is that the Holy Spirit cause them to record the sayings of Christ. The core teachings of Christ survived through human inadequacies, failures and possibly poor management because the Holy Spirit was actively guiding those unknown scribes.
The “Helper” or “Comforter” is the Spirit of Truth was sent to teach all things and bring to remembrance all things that Jesus have said. The same Spirit of Truth will testify of Him and bear witness of Him to His followers. The Spirit of Truth will guide us into all Truth. There is no room for error as long as the spirit of God is in control.
Howbeit when he, the Spirit of truth, is come,he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will show you things to come. He shall glorify me: for he shall receive of mine, and shall show it unto you.
Another role of the Holy Spirit is to convict a person of wrong a right (sin or righteousness). He gives a person a “conviction” to know whether a thing is right or wrong. It is like a spiritual radar that tells you whether you are off track or in track to your journey. Those people who wrote and transcribe the words of Christ (as they were written and read now) were given this spiritual conviction or we may say divine guidance to write the sayings of Christ.
The Gospel of Christ is universal in nature, it is for the whole world to hear or read. The flavor or color of the words of Christ may differ as they are translated to different languages but the “core truth” are the same. We can only fully understand the meaning of every word of Christ if are under the influence of the sweet Holy Spirit of God. We need to know more about the acts of the Holy Spirit than the church activities around us.
