What does the Bible say about the necessity of Jesus' departure?

In John 16:4-7, Jesus tells His disciples that it is to their advantage that He goes away. He explains that if He does not go away, the Comforter, the Holy Spirit, will not come to them. This departure is crucial because the Holy Spirit is sent to guide them into all truth and to convict the world concerning sin, righteousness, and judgment. Jesus emphasizes the importance of His mission and how the coming of the Holy Spirit will fulfill God’s plan in a way that His physical presence could not. The move from Jesus' earthly ministry to the Spirit's empowering presence was essential for the advancement of God's kingdom and the benefit of His disciples.
