The Privilege of Working in the Lord's Vineyard
personal vocation and mission defines the dignity and the responsibility of each member of the lay faithful and makes up the focal point of the whole work of formation, whose purpose is the joyous and grateful recognition of this dignity and the faithful and generous living-out of this responsibility.
In fact, from eternity God has thought of us and has loved us as unique individuals. Every one of us he called by name, as the Good Shepherd 'calls his sheep by name' (John 10:3). However, only in the unfolding of the history of our lives and its events is the eternal plan of God revealed to each of us. Therefore, it is a gradual process; in a certain sense, one that happens day by day. God gives us special graces so that our circumstances can be an occasion for loving him more and doing a genuine apostolate.
