26 But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you.
26 But [moreover]
Jesus now drew a distinction and not a contrast between His own teaching during His public ministry and that of the Spirit during the dispensation of the church (Ac 2:33).
The Greek idea of the Helper is Advocate. The coming of the Spirit would cushion the blow of Jesus’ departure from the apostles by interceding for them.
the Holy Spirit,
This is the only time the name “Holy Spirit” is found in the farewell discourse. The Greek says, “the Spirit, the holy one.” This puts stress on the idea that the Spirit is uniquely set apart. It is important to understand the distinctiveness of His person and character.
whom the Father will send in My name,
The Holy Spirit would come in Jesus’ name or in His authority. The Father, also, sent the Spirit (Jn 15:26). The Father and Son cooperated in the sending of the Spirit during the age of the church. He is the emissary of both the Father and Son. This is called in theology the doctrine of the procession of the Holy Spirit from the Father and Son.
“In My name” indicates that the Spirit was the officially designated representative of Jesus after His departure. He would act on Jesus’ behalf during the church age as the Advocate to both the Father and Son.
He will teach you [the apostles] all things,
The special ministry of the Holy Spirit to the apostles was to “teach.” The apostles had not understood much of what Jesus taught before the resurrection. They would grasp it more fully after the Holy Spirit came.
“All things” here means all things about Christ’s person and work. The role of the Holy Spirit was as an instructor who would enable the apostles to write Scripture and have the necessary information to establish the church. The teaching here also included things that Jesus did not teach during His public ministry. This is how the apostles would come to an accurate and complete understanding of truth so that they could write Scripture. The Spirit would complete the revelation brought by Jesus.
and bring to your remembrance all things that I said to you.
It is one thing to be taught but another to remember what we have learned. That was true of the apostles. They needed divine enablement to remember what Jesus taught them during His three years with them. This was crucial for the writing of the New Testament.
Jesus knew that the 11 had not completely grasped what He had taught. They needed a guarantee of the continuity of the content that He taught them by means of the Holy Spirit.
The Holy Spirit guaranteed to the apostles both previous and further revelation and its clarity.
The Spirit teaches from within. He would enable the apostles to recall both the words and concepts of Jesus. He would impress upon them crucial principles and prompt personal response to His teaching.
The Holy Spirit guarantees that we will receive the New Testament accurately and clearly. He gives continuity of revelation. The apostles were subject to the frailties of human beings. They forgot much of what Jesus taught and would need help writing the New Testament.
There is a tendency among believers to forget about Jesus’ love for us. Another issue is that, even if we have learned principles of life from God’s Word, we have a proclivity to grow stale in our appreciation for their value.
The Holy Spirit does not directly reveal new things to believers today; He brings to remembrance old things. He also rivets them in our mind if we open ourselves to His doing that. When we forget His teaching, the Spirit stirs up the vague memories and moves them into living reality. Then He rivets them into our memory.
We live in a day when evangelicals do not believe that they need to be taught. They want to live by their bootstraps, their experience, and not by clearly laid-out principles in God’s Word.
