First Steps in Holiness is an application that is aimed at all audiences in order to help take the first steps in this call that God makes us (cf. Lev 20,7); One cannot teach exactly how each one should be a saint, since it depends on the state of life, geography and difficulties that are different in the life of each person, but it can help to give the first push so that the person can already know how and where you have to go on your way.
