114. The chief cause was for the sake of the Word. This is because the Word is Divine truth itself, which teaches us that there is a God, a heaven and a hell, and life after death; it also teaches us how to live and what to believe, to enable us to reach heaven and so to be happy for ever. All of these points would be totally unknown without a revelation, which in this world means without the Word. Yet man was created in such a way that he could not die, as far as his interiors are concerned.# # Natural light by itself cannot yield any knowledge about the Lord, heaven and hell, how people live after death, or about Divine truths, which are a person's means of achieving spiritual and everlasting life (AC 8944, 10318-20). This can be established from the fact that many people, including the educated, do not believe in them, despite being born where the Word is known, and having been taught by it about these subjects (AC 10319). It was therefore necessary for a revelation to be made from heaven, since human beings are by birth destined for heaven (AC 1775).
