“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.
Jesus Our Substitute
Who could ever imagine sending an innocent person to be beaten and put to death in the place of a violent murderer? Nothing about that would be fair! Yet that is exactly what Jesus did. He died on the cross even though He was innocent, and Barabbas was set free even though he was guilty. Barabbas is a picture of us all — guilty before God and facing His judgement. But Jesus stepped in and became our substitute, paying our debt and setting us free!
