“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.
If someone bought you a new car, paid for it in full, and gave you the title, would you go to the dealership every month to make payments on it? Of course not! And yet that is exactly what we often do as Christians. Our sin debt has been paid in full and our record has been wiped completely clean, but we continue to live as though we’re guilty in God’s eyes. Once you understand the truth about God’s forgiveness, you will see your standing before Him in a whole new light, and you will be free to live your life for Him without being crippled by the guilt of your past!
