Selection from Arcana Cœlestia ~ Emanuel Swedenborg
The Word is a medium uniting man with the Lord; and unless there were such a uniting medium, heaven could not inflow with man; for without a medium there would be no unition, but heaven would remove itself away from man; and if this were removed, no one could any longer be led to good, not even to corporeal and worldly good; but all bonds whatever, even those which are external, would be broken. For the Lord rules the man who is in good by means of internal bonds, which are of conscience; but one who is in evil by external bonds alone; and if these should be broken, every such man would become insane; even as is the man who is without fear of the law, without fear for his life, and without fear of the loss of honor and gain, and thus of reputation — for these are the external bonds — and so the human race would perish. From all this it may be seen why the Word exists, and what the character of the Word is.
(Arcana Cœlestia 4217:3)
