Those which are the Lord's are called in the Word 'remnants', and here they are chiefly the cognitions of faith which a person has learned since he was a small child. These are stored away and do not come out into the open until he reaches this state. Nowadays this state rarely occurs without temptation, misfortune, and sorrow, which lead to the inactivity and so to speak the death of bodily and worldly concerns - the things which are man's own. In this way what belongs to the external man is segregated from what belongs to the internal. Within the internal are the remnants, stored away by the Lord until this time and for this purpose.
