John 14:15–31 contains a prediction about the Holy Spirit. Jesus refers to this as the Spirit of Truth, and promises that the Spirit will arrive to help the disciples carry on after Jesus is ascended to heaven. Throughout this section, a person’s love for Christ, their obedience to His teachings, and the indwelling of the Spirit are intertwined. As in prior statements, Jesus is focused on comfort and encouragement. He will continue to highlight the need to maintain faith, based on all He has said and done so far. Later, after advance warnings about what Christians will face, Jesus will return to describing the work and purpose of the Holy Spirit under the new covenant.
