Acts 1:5
For John baptized with water, but in a few days you will be baptized with the Holy Spirit — John the Baptist's ministry provided the symbolic preparation; Jesus provides the real transformation. The contrast (water/Spirit) echoes Joel 2:28-32 and John 7:37-39, showing fulfillment of OT hopes for the outpouring of God's Spirit. This baptism will empower all believers, not just leaders, democratizing prophetic experience.
