For The Son is in The Father and The Father is in The Son.
In another place in the Bible is the hint that refers to Jesus could not sin because His seed remained within Him, His Godness remained within Him thus He could not sin because that would be contrary to Whom God IS.
Jesus let us know that The Seed left Him at the end on the cross, so that He could die in our stead. I happen to believe that The Seed came back into the body in the tomb, and He left the wrappings and the rock enclosure by just stepping out of our spacetime limits.
BTW, we are told that the earnest of our inheritence of That Seed is what comes into our human spirit when saved, so that we have 'God with Us' for the remiander of our earthly life. But the degree of expression of His 'within us' is related to how much we allow Him to 'do it' ... Faithful is He that calleth you, for He will also do it.
Thank you so much for all your insights, dear MHGinTN!
