Ephesians 5:18 says, “…be filled with the Spirit” as a command from God in the present, passive tense.
Knowing the original Greek context of this passage allows us to observe the three important points of being filled with the Holy Spirit. First, it is an imperative of command – this means that God isn’t suggesting, but rather insisting. Next, it is not something that happens once, but rather continues as action… “Be continually filled.” Additionally, this is something that you cannot do yourself. The passive voice tells us that we are being acted upon – God is the agent of the action and we are the recipients. An amplified version might read, “I command you to continually allow God to fill you with His Holy Spirit.” Be filled!
