We know that this world is not all there is, but that there is a spiritual world too. We also know that the two worlds are connected as one. Then where is the place we are to settle down ultimately? We are now living in the flesh, but we are moving toward the eternal world. We go through our teenage years, our twenties, thirties, middle age, and old age. We go through hills of different ages and eventually go down like the sun. But those who know that the spiritual world exists understand that our life in this world is short, and the next world we enter after death is eternal. Hence, physical life is a time to prepare for the eternal world. Isn't that how it seems?

For instance, in school there is a standard of achievement for students. How much a student has achieved according to this standard determines how much he is recognized in school. The greater the gap between his points and the full score, the farther away he drifts from the standard. Everything is determined by a certain standard.

Our physical life is like a time of preparing for good grade points at school. We seek good grades for our entire life and want to bring good results in our necessary responsibilities throughout our whole life. We evaluate our daily life according to a certain standard. Ordinary people do not think about that. They simply think that since they are born, they live with their parents at home and are just like any other people. The center of such a life is physical necessity: food, clothing, and shelter. Isn't that how they live? But we Unification members know clearly that the spiritual world exists. We do not just believe it, we know it. How do we know it? Through many experiences. In our living environments there are undeniable historical and realistic facts. As we established our global foundation, we had many experiences.

Therefore, Unification members cannot deny the existence of the spiritual world. (140-121)
