The power of God is not offered for our tribe, our kingdom, or our gain. Christ’s ascension is just another necessary action of God in critique of the self-motivation of disciples. Christ once more calls us to be prepared for the Spirit to lead us in dispersing power as we share God’s love with all persons, even to the ends of the earth.
The disciples are given a purpose, they are given a mission, but Christ tells them to wait, for they do not yet have the power from on high. Sometimes waiting is a necessary thing.
