Before God calls any person to do a special mission for God, or even a lifetime vocation, He ensures that the condition in the person's heart is ready for the "Yes," or at least for the "partial Yes" that responds to His invitation, "Come and see." If the verbal cue on the call comes, either from a cleric, a religious, a parent, a friend, or anyone else, the person automatically knows that the time has come for a "Yes." If the person being told that he is called to this and that cannot confirm that call internally, he needs to be very careful because the Lord may not have called him in that direction pointed out.
