By associating what Jesus preached to people with both history and modern times, some universal truth in His teaching can be found. Read through the book, and you may understand that building a harmonious and prosperous world is the common aspiration of all people in the world, regardless of race or nationality. Jesus and Mohammad are both bridges between God and human beings, as well as bridges between the ideal and reality. Communism is another name of worldly heaven. Believing God, aspiring to worldly heaven and seeking communism are both pursuing the highest standard of truth, virtue, and beauty. Therefore, instead of fighting for a different name, people with different beliefs should promote communication and understanding and develop together.
