But what this means is that wherever God’s paradise is, wherever the dwelling-place of God is, that place is going to be under siege by the enemies of God, by the spiritual enemies of God. That includes within us. This is part of the basis of our understanding of spiritual warfare. If the Holy Spirit is dwelling within us and we’re the temple of God and we’re the dwelling-place of God, then we become paradise within and the mountain of God within. Then that means there’s going to be a siege; we’re going to be under attack by God’s enemies. So this forms an important base, deeply connected to our understanding of spiritual warfare. The mountain of God is not some physical mountains, but it’s inside you. It’s part of your internal geography.
