Oh shucks. Now I'm going to have to think about it all over again. I get the "image" of indwelling, but I'll have to think about what it means. If the spirit "moves in", presumably (whether it's by grace or not and whether it's permanent or not) would there be a kind of "welcome" or "hospitality" or somesuch. Gotta think about it. Is 'indwelling" a big, rich concept in Protestant theology?
Dang! Gotta go polish my shoes for church!
What IF humans were spirits all along in a body suit.. and what you see in a mirror was not YOU but the body suit.. And life on this planet was a matter of IDENTITY.. identifing with the flesh or identifing with "the Spirit"... AND thats(IMO) what Jesus was/IS trying to educate to a very "fleshly" people..
How else could every human that ever lived live for eternity.. unless we are merely spirits being "TESTED/GRADED".. for some future tasks.. (heaven and hell)... This flesh suit is a pretty good dequise I would say.. What a grooovey plan, if true..
If I'm following you, then I would say that indwelling is a very big deal for us. We see Him as the permanent seal of our salvation, and even further, as a "brand" upon our heart. We are "marked" forever, so that anyone checking can see that we belong to the stable of Christ. :)
As for when the Spirit moves in, there would have to be a welcome, under our view, because true belief immediately preceded it. The believer just got through asking Christ to come into his life to be Lord and Savior, so when the Spirit immediately indwells, it is always a welcome act.
