“be filled with the Spirit” (Ephesians 5:18) is to be controlled by the Holy Spirit. This is a present continuous action and requires a believer to be (a) daily yielded to God, (b) daily in repentance with confession with godly sorrow, (c) daily allowing the word of God to richly indwell the inner man. Being controlled by the Holy Spirit empowers a believer (a) daily in spiritual battle (Spirit versus flesh) and, (b) daily in living out the person and character and conduct of Christ and in being obedient to the will of God.

Holy Spirit: Spiritual Power
The power of the Holy Spirit is illustrated by (a) inspiration of scripture, (b) illumination of hearts, (c) regeneration of a believer, (d) indwelling presence in a believer, (e) baptism into the body of Christ, (f) sealing and giving of a pledge in a believer and, (g) filling in a believer.
