The Holy Spirit will bear witness that they have been with him from the beginning. He will keep them from falling away. They were to remember what Jesus had told them. Where they were going, they would be sorrowful. However, the Paraclete would come to convict the world about sin, righteousness, and judgment. The Spirit of truth would glorify Jesus. The Father would give them what belongs to Jesus. Do you believe in the Paraclete, the Holy Spirit?
