From where can the Kingdom of Heaven begin? Without comforting the sorrow of God, we cannot go into the Kingdom of Heaven. Because fallen humankind has been creating a sorrowful history since the fall until now, we must personally seek out all of the sorrowful bonds of history. We must find all of the bonds of the six thousand years of history since Adam and Eve. That which exists to teach about the God of sorrow is the Principle of the Unification Church. If there is sorrow, the people of the world despise it and run away. It is the Principle of the Unification Church that teaches about the sorrow of God, which contains more heartbreaking situations that any other sorrow.

In the world, if there is a sad occurrence everyone avoids it and runs away. But the Unification Church's Principle's essence is to go through this sorrow. In the world, when there is a sad occurrence everyone tries to evade it, but original humankind is made not to do that. If we know about the sorrow of God, it actually makes a great strength appear. The more we know about the pitiful circumstances of God, the more the source of strength to resolve it becomes an unlimited explosive source of motivation. This is the extraordinary strength which the Unification Church possesses. (21-113)

We need to know what God's purpose was in the past. We need to know what God's direction, situation and heart were like in the past. Then we need to know God's purpose, direction, situation and heart in the present, and God's purpose, direction, situation, and heart in the future. If we accomplish this, humankind will naturally reach perfection.

So what does the Unification Church teach? From the standpoint of the providence, it teaches the purpose, direction, situation, and heart of the God of the past, of the God of the present and of the God of the future. As the purpose refers to the substantiation of the idea, and the direction refers to actions, the purpose and the direction must be in unity. The situation refers to daily life, and the heart refers to relating. (16-141)
