Joy is an important factor in human life. It is indispensable in giving a positive sense to human existence, in enlivening everyday life; it is also important in the process of man’s self-improvement. It exerts a big influence on one’s somatic and psycho-spiritual health and that is why one may refer to it as a healing element. It is a strength which removes inter-human barriers which unites and creates a community. It is based on friendship and love. Thanks to joy, man finds it easier to forgive others and is able to love his neighbor. The source of Christian joy is Jesus himself, who is revealing God Father. The mystical experience of St. Sister Faustina, described in her Diary is conferring the possibility of truth joy coming out from the experience of God in the contemporary world.
