Revelation is progressive—throughout Scripture we see the Lord revealed consistently. Everyone who belongs to Him is a candidate for the Spirit, and nothing can disqualify you. While not all have the gift of prophecy, every believer can prophesy.
The Spirit within marks our identity, while the Spirit upon empowers us for service. Both are the same Spirit at work in us. The gifts of the Spirit are given for ministry, and every believer should desire them.
Earnestly covet the gifts of the Spirit.
