“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.
There is a tendency in human nature to take for granted the sacrifices that have been made for us during our lifetime. We often forget the blood of the patriots who gave their lives defending our freedom. We often forget the martyrs who gave their lives defending the Gospel. But are we also guilty of forgetting the greatest sacrifice ever made for us when Christ gave His life on the cross?
