“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.
The Spiritual Man
God has a plan and a purpose that He is bringing to pass. Through the ages, there are different degrees to which the world has experienced God; Innocence, Conscience, Human Government, Promise, Law. Living in the age of grace now, our experience with God is dependent upon our cooperation with the Spirit of God. We cannot gain true wisdom, knowledge, understanding, or counsel without the Holy Spirit. We must learn to trust Him over our own senses and understanding. We will only begin to trust Him over our own senses if we know who He is. We will only know who He is, when we choose to read His word, trusting His Spirit to reveal to us who He is.
