The loss of faith in the contemporary seems to have become an indisputable
fact, but also caused a wide range of social concern. Endless material needs not
only alienate people, make people fall into the trap of egoism, sensualism and
consumerism, distort people's social nature, but also cause great pressure on the
ecological environment, make the living environment of human beings increasingly
pollution and deterioration, make the sustainable development of human beings
seriously hindered. At the root of it is that in the development of human history, faith
has become indifferent, or material enjoyment has become the primary faith. This
paper takes the essence of moral belief as the starting point, discusses how moral belief
is possible and how to rebuild it in contemporary real life, and hopes that in any case,
people can play the role of moral purification, self-policing, introspection and self-
discipline.
