During the period when God was depicted on stained glass, the concept of “God” dominated people’s minds. Today, for the many people for whom religion is not the backbone of spiritual life, life is determined by their own free will, rather than living with a shared commonality. This has created a situation in which the differences between people has become more distinct, making it difficult for them to have a mutual understanding of one another. However, if we were to recall the fact that we are the same human beings, and that we all share the same history of humankind, it should not be difficult for us to understand one another.
