525. Many people who arrive in the other life from the Christian world bring with them a faith that they are going to be saved out of straight mercy, because they plead for it. When they are examined, though, it turns out that they have believed that getting into heaven was simply a matter of being let in, and that people who had been admitted were in heavenly joy. They have had no notion of what heaven is or what heavenly joy is. So they are told that the Lord does not deny heaven to anyone. They can be let in if they wish and even stay there. Some who wanted to were actually let in; but at the very threshold, at the touch of heaven's warmth (that is, of the love angels are engaged in) and the inflow of heaven's light (which is divine truth), they were seized with such pain in the heart that they felt themselves in the torments of hell rather than in the joys of heaven. Struck by this, they plunged down headlong. In this way they were taught by firsthand experience that no one can enter heaven out of straight mercy.

10. Every multifaceted entity falls apart unless it depends on one thing, a fact recognized by all sound reasoning whether religious or not. For example, a human being, made up of many limbs, internal organs, sensory organs, and motor organs all interconnected, would fall apart if it did not depend on one soul; and the body itself would fall apart if it did not depend on one heart. A country would fall apart but for its one monarch; a household would fall apart but for its one head; every one of the many workplaces in every country would fall apart but for its one person in charge. What army would prevail against its enemies without a leader who has supreme power, and officers with authority over their soldiers? Likewise a church would fall apart unless it acknowledged one God; and even the angelic heaven would fall apart. Heaven acts as the head of the church on earth; the soul of both is the Lord; this is why heaven and the church are called his body. So if heaven and the church did not acknowledge one God, each would be like a lifeless corpse that would be thrown away and buried because it was good for nothing.
