A good community is essential for the spiritual life. Therefore all the time we are to pray and ask the Holy Spirit to build our unity. The Christian community is based on the example of the unity in the Holy Trinity. The Son of God tried to create and protect such a community among his disciples. However, it always depends on each person whether he wants to be in the good relationship with God and other people. For everyone has free will and is able to choose his friends by himself. The proper relation with God and people gives peace and joy to the heart. The inner unity with God defends from the Evil One and helps to progress in holiness. The man who is united with the Holy Spirit knows what is his vocation and the aim of his life. For that reason, it is good to be consecrated and joined with brothers in order to enter the kingdom of God.
