Pope John Paul II describes the vocational call as a dialogue between us and Christ:
In the hidden recesses of the human heart the grace of a vocation takes the form of a dialogue. It is a dialogue between Christ and an individual, in which a personal invitation is given. Christ calls the person by name and says: "Come, follow me." This call, this mysterious inner voice of Christ, is heard most clearly in silence and prayer. Its acceptance is an act of faith.
