He came back physically, in a glorified body. His glorified body is not temporary, it is just exists in a dimensional variable greater state than we now perceive. So when He appeared in the Upper Room after His resurrection He was "at" the Upper Room before He stepped into the spacetime of the Upper Room.

The analogy is understood like a three diemnsional spatial object is only sensed by a two spatial dimensional being only where the three variable object is "in" the two variable realm, the intersection point between the three and the two. The scene in Daniel chapter five illustrates this "intersecting" as the being to whom the hand belonged had only the hand in the spacetime of the palace party central writing on the wall. But the being exists physically in some where/when undetected by the partiers except where He reached nto their spacetime to write on the wall.

I use the term spacetime because this other variable dimensuional realm, has space and time but with more variable expression than our current perception state. In the analogy by adding one more variable expression the three variable object is invisible to the two variable being except where the three intersects the two variable realm. The being writing on the wall in palace party central was "in" the spacetime of the palace only "AT" his hand /wrist /arm. "Add" one more variable of space and/or time and the 'thing' is no longer perceived by our limits state as we are fashioned now. At the moment of the Rapture of all believers we will be transformed int he twinkling of an eye into beings with more variable expression, in glorified bodies invisible to beings in the world around us. THEN we will be caught up together with the dead in Christ who have been given new glorified bodies and souls, to meet the Lord as He is now,(1 John 3:2) in the air.

An interesting post, and I’m not disagreeing with you.

It’s a very interesting topic, and we will all find out some day soon.

Just getting back to the original topic, I ask the question:

Could a deceased father come back as an “orb” or spirit of some kind to comfort the newborn son he never met in the flesh?

Nothing I believe (and I am Christian without qualification - Jesus is my Savior and Lord), or have read in the Bible, or have seen written in the responses of other believers here, would say that he definitively could not.

So, yes, it could happen. I just don’t think we humans know enough about the topic right now to say it could not happen.
