“Be filled (the filling of) with the Holy Spirit” is commanded of every believer for empowerment (Ephesians 5:18). The filling of the Holy Spirit is quenched (1 Thessalonians 5:19) or grieved (Ephesians 4:30) when the believer sins. The believer is filled again, back to capacity from a diminished state, by naming his/her personal sin(s) to the LORD (1 John 1:9) if necessary. Do not confuse the temporary “filling” of the Holy Spirit with the permanent “indwelling” of the Holy Spirit.
Further clarification: The filling of the Holy Spirit produces spirituality (Ephesians 5:18) and is therefore, the power source of God for believers. The Holy Spirit uses Bible doctrine metabolized in the soul to convict, motivate, and direct our thoughts and actions. But we must attempt to remain in fellowship by naming (and removing from our lives) perpetual sin when we stray.
The spiritual battleground of the believer is in the soul. This spiritual warfare is constant for control of the soul. The believer’s worst enemy is the fleshly self (the sin nature). Therefore, the filling of the Holy Spirit is imperative to victory in the Christian life.
Does the believer glorify Christ? If your answer is yes, your answer should be: The Holy Spirit glorifies God (John 16:7b). The mentoring and power of the Holy Spirit in the believer when filled (in fellowship) is how Christ is glorified. Christ Himself stated this in John 16:14 (Reference John 7:9).
Jesus Christ, by the mentoring of the Holy Spirit, is being formed within you (Galatians 4:19). In the filling of the Spirit, Christ shines in you (fellowship). When Christ shines in you, He shines out from you for the world to see.
