A Random Thought to Ponder

Jesus frequently refers to the fact that He is in the Father and the
Father is in Him. This is a level of intimacy incomprehensible to us.
It's also a necessary mingling. Otherwise there would be boundaries
between the Persons of the Trinity. Even if you imagine 0 width
boundaries there would exist the possibility of one Person pulling
away from the others, and what would be in the gap?
