Gate
Gates" in ancient times had a significance that does not hold in the modern world. Cities then were enclosed by walls for protection; gates in the walls let people in and out to do their business, but were also the weak points in the cities' defenses. In the Bible, cities on one level represent the minds of individual people. On a broader level, they represent beliefs shared by a community. The gates, then, represent openings where the Lord can feed us an understanding of truth and a desire for good. They also represent points where the hells can invade and sway us with false ideas and evil desires. We are kept in balance during our lifetimes, with influences from both the Lord and from hell. Ideally, we will over our lifetimes continue to invite the Lord farther and farther in and drive the hells back until ultimately the Lord can occupy our minds completely. And that point our belief in Him and His power and love will hold the gates and deny evil any entrance. As individuals, we at that point become angels. As communities, we at that point become part of the Lord's church. And at that point the gates become an entry point, introductory truths that allow people to enter churches and start bringing the Lord into their lives.

2589. THE STATE AND CONDITION IN THE NEXT LIFE OF NATIONS AND PEOPLES BORN OUTSIDE THE CHURCH
It is commonly supposed that those born outside the Church, who are called heathens and gentiles, cannot be saved for the reason that they do not possess the Word and so do not know the Lord, without whom there is no salvation. But that gentiles too are saved may be known from the single consideration that the Lord's mercy is universal - that is, it reaches out to every individual human being. For gentiles are born human beings the same as those within the Church, who are a relative minority; and they are not to blame because they do not know the Lord. Consequently the nature of their state and condition in the next life has in the Lord's Divine mercy been shown to me.
