It is good to have faith. Many contemporary people have no faith, so there is a lack of faith in society. Leave the individual alone for the time being, because it varies from person to person. At the social level, the main factors to maintain social stability are morality and law, and social security measures. A lot of morality is based on religion, but when the law comes into effect, it has often done harm to society. The social security system can only be a condition to reduce crime, but it cannot eliminate the motive of crime from the source. Take the law as an example, it not only causes damage when it plays its role, but also is restricted by many factors such as absolute justice and law enforcement personnel. Moreover, many religions believe in karma, believe in the existence of God, and fear God, who is everywhere. Based on this, faith should come from inner consciousness and stick to the bottom line. Therefore, religion should be conducive to the stable development of society.
