Why does spiritual restlessness drive people to join the Catholic Church?
In modern time, as has been the case most of the time, people get deeply involved in endless chores of life, get engaged with various mundane luxuries to the point that they deliberately ignore the presence of the Divine Power that controls every minute details relevant to daily affairs.
People are regularly involved with concerns relevant to securing financial affairs, among others, to ensure a decent life at a time when turbulent affairs stand in the way and difficulties continue to emerge from time to time.
