Hard as it may be to believe at times, the New Testament informs us that we who live after the ascension of Christ to the right hand of God the Father are in a better position than the disciples were when Jesus was walking the earth. This is because we live in the day when the old covenant promise that the Spirit would come in His fullness has been realized. At Pentecost, Christ poured out His Holy Spirit on the church, the Spirit of truth who guides us into all of the Lord’s revealed will (Joel 2:28–32; John 14:17; Acts 2:1–4).
That we are in a better position today than the disciples were when Jesus walked the earth is an implication of today’s passage, which is part of a lengthy discourse about the person and work of the Holy Spirit. Speaking to His apostles, who are about to go through a great trial as the Teacher is arrested, humiliated, and executed, our Savior encourages His followers with the news that He will be sending them another “Helper” (John 14:16). The meaning of the term Helper is multifaceted, but part of the sense is that the Holy Spirit will come as our advocate — as One who will stand with us and for us. At least partly in view here is the Spirit’s role to stand with us in persecution to give us wisdom and the strength to speak the truth even when our lives might be on the line (Matt. 10:16–22).
Jesus ties the new covenant experience of the Holy Spirit to our love for Him that manifests itself in obedience to His commands (John 14:15, 18–24). It is not that by our love we earn the gift of the Spirit, only that loving Christ is more than just words. The Holy Spirit, because God first loved us, puts love for Jesus in our hearts and makes us willing to follow His way (3:1–8; 1 John 4:19). In turn, as we exercise this love, we enjoy a fuller experience of the Spirit’s grace and power.
This fuller experience includes a deeper knowledge of the Lord’s truth. In John 14:26, Jesus says the Holy Spirit will teach us all things and remind us of all He has taught. In context, since the first hearers of these words were the apostles, Christ is probably referring primarily to the inspiration of these apostles to write sacred Scripture. Secondarily, He is speaking of the Spirit’s ministry to illumine the Word so that we might understand it, recall it when needed, and put it into practice.
