Dr. Joel turns to Paul’s writings, especially Ephesians, to reveal the Spirit’s ongoing work in the Church. The Holy Spirit seals believers as God’s own, guarantees their eternal inheritance, and builds them into a living temple where God dwells. He explores how the Spirit shapes humility, unity, and holiness within God’s people, empowering them to live worthy of their calling. The Spirit doesn’t just mark our salvation, He leads us daily toward Christlikeness, reminding us that the Church is not a building but a Spirit-filled body formed for God’s glory.
