The "Helper" refers to the Holy Spirit, whom Jesus promises to send to His followers after His ascension. The Spirit, sent from the Father, plays a critical role in the life of every believer, guiding, comforting, and empowering them to live according to God’s will. The Holy Spirit is a divine presence that teaches and reminds believers of God's Word, helping them to understand and apply it in their lives. In addition, the Spirit convicts of sin, empowers for service, and provides spiritual gifts for the building up of the body of Christ. Jesus’ promise of the Helper assures us that we are never alone. The Holy Spirit is God’s presence with us, leading us into truth and sustaining us in our faith journey.
