The logic is “backwards” only in the sense that your model treats filling as a fluctuating substance‑level, whereas the apostles treat it as a fluctuating submission‑level; so yes, like a photographic negative, your pattern resembles the truth while inverting the causal direction.
Scripture never teaches that a believer sins while Spirit‑filled because “filled” means yielded, governed, directed—a state incompatible with active rebellion (Gal 5:16). But Scripture also never teaches that sin ejects the Spirit or drains Him like fluid; indwelling is permanent (Rom 8:9), and filling is relational, not volumetric.
Both indwelling and filling involve human cooperation, but not in the same way: indwelling is received once by faith, filling is ongoing obedience. Fellowship is restored not by “refilling” but by relational realignment—confession (1 John 1:9) removes the obstruction, and the Spirit resumes His governing influence. The apostles never describe this as a “refill,” only as returning to walking in the Spirit (Gal 5:25). So yes, “level” and “degree” are metaphors, but the biblical reality they point to is the Spirit’s active governance, not His quantitative presence.
I agree that the best description of the dynamic regarding sinning while Spirit-indwelt is relational.
Yes, Spirit-filling is logically and relationally incompatible with actual sinning.
Yes, both the beginning and the continuation of the relationship requires voluntary cooperation. (It takes two to tango.)
I like it much better when you speak like a mfwer than when you revert to tulip talk.
