Ephesians 5:18:
And do not get drunk with wine, for that is debauchery, but be filled with the Spirit, [ESV]
And be not drunk with wine, wherein is excess; but be filled with the Spirit; [KJV]
and be not drunk with wine, in which is dissoluteness, but be filled in the Spirit, [YLT]
Some readings of Ephesians 5:18 understand the Spirit as analogous to a kind of "liquid spiritual substance" that one could be filled with, similar to how one is filled with physical wine, which is mentioned for comparison purposes in the same verse. Others interpret that the Spirit of God has personhood/sentience (possibly based on other passages, e.g. here and here).
Question: if we assume as a premise that the Spirit is a person, then how can we make sense of the phrase "filled with the Spirit"? How can someone be "more filled" or "less filled" with the Spirit if the Spirit is a single, indivisible person? Or should we see the Spirit as both a sentient person and a divisible substance?
