Being Filled with the Spirit

Apart from the truth in verse 18, which is the heart of Paul's message, the book of Ephesians would appear to be legalistic. Every exhortation he gives would have to be fulfilled through the power of the flesh. Believers would need to rely on their own resources and strength to follow the great road map of the Christian life that the apostle presents in chapters 4–6—and would, of course, find themselves completely deficient. Christians cannot walk in humility, unity, separation, light, love, and wisdom apart from the energizing of the Holy Spirit. To walk without the Spirit is to walk unwisely and foolishly (see vv. 15–17). We can “be imitators of God, as beloved children” (5:1) only as we are filled with the Spirit (cf. John 15:5). . . .
