The need for a vision of an ideal future and a sense of meaning is essential for individuals' happiness and well-being, even for those who are not religious or do not believe in God. Communists were religious in their belief in a new utopia, and this illustrates the importance of having a vision for the future.
The concept of religion and belief in God has been closely linked to the human pursuit of happiness, with many studies emphasizing the positive correlation between the two. Religious values such as service to God have been found to contribute to overall life satisfaction.
The belief in an ideal vision of utopia, whether it be religious or secular, is a common human need, but can lead to dangerous fanaticism.
