The Anticipation Of The Spirit
As the disciples prepare to travel back toward the region of Jerusalem for the culmination of the forty days, the Master's teachings are focusing heavily on the "Promise of the Father." He has commanded them not to leave Jerusalem once they arrive, but to wait for the baptism of the Holy Spirit, which will empower them for global witness.
This promise shifts their perspective from what they can accomplish to what God is about to do through them. The physical departure of Jesus is no longer viewed as an abandonment, but as a necessary step for the arrival of the Helper. The disciples are learning to live in a state of active, expectant waiting.
— Acts 1:4
