“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.
In Luke 17 Jesus heals ten lepers but only one returns to gives thanks. Though Jesus did not command them to return and give thanks, he was surprised that only one did; and that he was a foreigner. What can we learn about being thankful from this? Was this man simply being respectful, or was there more? Why should we be thankful, and what does that mean?
