Without the Holy Spirit, Christian discipleship would be inconceivable, even impossible. There can be no life without the life-giver, no understanding without the Spirit of truth, no fellowship without the unity of the Spirit, no Christlikeness of character apart from his fruit, and no effective witness without his power. As a body without breath is a corpse, so the church without the Spirit is dead.

—John R. W. Stott, The Message of Acts: The Spirit, the Church & the World, 60.
