Jesus Left so...
Jesus advised His disciples that He must be sacrificed so that He could send the Parakletos (the Comforter), Who would continue His ministry:
... I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send Him unto you (John 16:7 KJV).
So, the Spirit's role was to shift from directing people from the outside to living within believers and guiding them from the inside.
This is Biblical, as Christ had to be sacrificed first for the Spirit to continue His ministry. The Bible verifies the approaching personal indwelling of God
the Holy Spirit.
This is better, as it is more effective to start at the center of our affection. At our control center.
Now the Believer has the indwelling presence of God, the Holy Spirit, because Jesus was willing to move over.
If we will move our self out of the way, the Holy Spirit will be there to guide us and empower us.
“Lord I send myself away that you may have the freedom to work in me and through me.”
