In the new heaven and new earth, I read somewhere* that while we will see more fully, that sight will come in significant part through each other. We're all needed.
Of course this is according to the revelation and truth God makes available to us.
This begins now in the new creation in Jesus, something even rooted in the old creation. Yes, we need each other, true around the world now, true in the fellowship of believers now all around the world, and someday true in a marked sense in the love of God lived out in the new creation in Jesus in the new heaven and earth.
What thought might you like to share on this?
(*Actually from C.S. Lewis, though doesn't seem to be in a book of his I'm reading now. But if I can find it, I'll share the quote tomorrow.)
