Marriage #48
48. Those of them who are in the heaven of the Mohammedans have only one wife, having rejected more. For there is a Mohammedan heaven distinct from the Christian heaven. But those who eventually, as many do, acknowledge the Lord as one with the Father are separated and are in heavens which communicate with the Christian heavens; and they have conjugial love.
Midst
The "midst" of something in the Bible represents the thing that is most central and most important to the spiritual state being described, the motivation that drives everything else. In general this will be something we love or feel, because at the core of things we are what we love; our loves define us.
