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.

2117. THE LAST JUDGEMENT

Few nowadays know what the Last Judgement is. They imagine that it is going to be accompanied by the destruction of the world; and this leads to conjectures that this earth, together with everything else in the visible world, is going to be destroyed by fire. They also conjecture that then for the first time the dead will rise again and appear for judgement, and the evil are to be cast into hell and the good to rise up to heaven. These conjectures are based on the prophetical parts of the Word where references are made to a new heaven and a new earth, and also to a New Jerusalem. Such people do not realize that the prophetical parts of the Word have a meaning altogether different in the internal sense from what appears in the sense of the letter, and that 'heaven' is not used to mean heaven, nor 'the earth' to mean the earth, but the Lord's Church in general, and as it exists with each individual in particular.
