Why is the Holy Spirit's presence more important than Christ's physical presence?

Jesus indicates in John 16:7 that it is better for Him to depart so that the Holy Spirit can come. The rationale behind this profound truth is that while Christ's physical presence was limited to one location, the Holy Spirit can indwell all believers globally. This allows the work of God to be accomplished in a more expansive and powerful way. Through the Holy Spirit, Christians experience comfort, guidance, and empowerment to live out their faith. The presence of the Holy Spirit among believers epitomizes the fulfillment of God's covenant promise to be with His people, a reality far more beneficial than Christ's bodily presence could provide.
