It bears repeating before we look at an essential aspect of being “filled with the Spirit” that this “filling” is not something that can be achieved by willpower, determination, self-discipline, or “grit.” It is the natural result of a redeemed life yielded to the Lord Jesus Christ and moment-by-moment control by the Holy Spirit. If you are not born-again by faith in Jesus Christ, then all the self-help or self-reformation programs will not produce eternal life. (Read John 3:3-18 for a clear explanation of how faith alone can produce eternal life.)
Lewis Sperry Chafer offers us this gem on the meaning of being filled with the Spirit: *
“It is important to note that three times in the New Testament the effect of strong drink is put over against the Spirit-filled life (Luke 1:15; Acts 2:12-21; Ephesians 5:18). As strong drink stimulates the physical forces and men are prone to turn to it for help over the difficult places, so the child of God, facing an impossible responsibility of a heavenly walk and service, is directed to the Spirit as the source of all sufficiency. Every moment in a spiritual life is one of unmeasured need and super-human demands, and the supply of enabling power and grace must be as constantly received and employed. “As thy day, so shall thy strength be” (Deuteronomy 33:25).
“To be filled with the Spirit is to have the Spirit fulfilling in us all that God intended Him to do when He placed Him there. [See previous posts on Regenerating, Indwelling, Baptizing, Sealing.] To be filled is not the problem of getting more of the Spirit: it is rather the problem of the spirit getting more of us. We shall never have more of the Spirit than the anointing which every true Christian has received. On the other hand, the Spirit may have all of the believer and thus be able to manifest in him the life and character of Christ. A spiritual person, then is one who experiences the divine purpose and plan in his daily life through the power of the indwelling Spirit. The character of that life will be the out-lived Christ. The cause of that life will be the unhindered indwelling Spirit (Ephesians 3:16-21; II Corinthians 3:18).
“The New Testament is clear as to just what the Spirit would produce in a fully adjusted life, and all of this revelation taken together forms the Bible definition of spirituality. These undertakings are distinctly assigned to the Holy Spirit, and are His manifestations in and through the Christian.” [Emphasis added.]
