And now, the Holy Spirit desires to enter our souls, like then [Pentecost], but He honors our freedom, He does not want to violate it.
He waits for us to open the door on our own, and then He enters our soul, and He will transfigure it.
When He comes to dwell within us, the whole region of our soul is Christ, and then all problems, all delusions, all worries flee.
Then sin also flees.
