According to the words of Christ through His
apparitions to Saint Margaret Mary Alacoque, there are several promises
to those that practice the First Friday Devotions.
"In the excess
of the mercy of my Heart, I promise you that my all powerful love will
grant to all those who will receive Communion on the First Fridays, for
nine consecutive months, the grace of final repentance: they will not
die in my displeasure, nor without receiving the sacraments; and my
Heart will be their secure refuge in that last hour."
