What does the Bible say about Christ's departure?

According to John 16:5-11, Christ acknowledges the sorrow of His disciples regarding His departure, but emphasizes that it is expedient for them that He goes away. His going is not just a physical departure; it signifies a profound spiritual transition where He will send the Comforter. This Comforter, the Holy Spirit, will guide, teach, and convict the church regarding sin, righteousness, and judgment. Therefore, Christ's departure is central to the redemptive plan, paving the way for the Spirit to enact God's promises through the Church and effectively bring salvation to His chosen people.
