"Be filled with the Holy Breath" (Eph 5:18). Sanctification is literally the physical filling of your body from head to toe with a physical substance named the Holy Breath (traditionally misnamed the Holy Spirit) precisely as water, or smoke, or any physical substance fills a glass. Note that a smoke-filled container is not completely full ('sanctified') for lack of density.
Hence the principal duty of the Christian is to
wait upon the lord, that is, to PETITION God for outpourings of the Third Person (also called revivals), for "How much more will your heavenly Father give the Holy Breath to those who
ask him" (Lk 11:13). Note this is the only instruction given anywhere in Scripture as to how to receive the Third Person. And it was recorded by Luke who wrote more about prayer than anyone, including Pentecost which itself was a perfect example of Lk 11:13.
The OT made it clear that holiness is not obedience. Holiness is receiving an outpouring. "Then the Cloud covered the Tent of Meeting, and the glory of the Lord filled the tabernacle". "The tabernacle shall be
sanctified by my glory" (Ex: 29:43).
Notice that obedience wasn't involved. The tabernacle wasn't made holy by obeying God but by RECEIVING an outpouring of the Holy One. Again, "Take off your shoes, Mose, for you stand on holy ground." Why was the ground holy? Was it obeying God? No. The divine Fire in the bush radiated ('outpoured') divine Light quanta even onto the ground, making it holy. It was an outpouring.
Does this mean we can continually disobey God? No. If we disobey our conscience, we grieve the Holy Breath, and thereby forfeit outpourings. The point here is that we should not make the mistake of the Galatians - the mistake of thinking that sanctification proceeds by reading a bunch of commands/laws in the Bible and obeying them. Sanctification is principally a matter of waiting upon God for outpourings. That's the whole point of the Galatian epistle, especially of chapter 3, although the church hasn't understood this.
Take regeneration for example. It's an impartation of holiness and thus it's your initial sanctification. "The old is
gone, the new is come." Did you purify yourself? If so,how? By perfect obedience? Nope. It's a work of God. Problem is, it was only the initial sprinkling, only part of your heart is sanctified, it is not yet FILLED FULL of the Holy One. This is what Paul told the Galatians, "Having begun in the Holy Breath, are now trying to mature by human effort?" You began by RECEIVING Him for regeneration. Therefore you mature by RECEIVING more of Him - not by human effort.
