You make good points. The following verses show that Jesus Christ is indeed present in the world:All put Jesus' resurrected form in one specific place...at the right and of God in heaven. The last (Acts 7:55-56), the story of the martyrdom of Stephen, indicates that Stephen sees him there as he is dying. So I think that's pretty much incontrovertible evidence of where Jesus is at the moment.

You can probably think of a few more verses that I didn't list above. The second person of the Trinity was omnipresent before the incarnation. Why should He be limited now? But even physically, as a Lutheran you believe He is physically present in the sacrament of the Eucharist.
How can you explain this?
