 Mary is truly holy and the mother of the second person of the Blessed Trinity, which is, of course, Jesus. The last part of the Hail Mary, pray for us sinners now and at the hour of our death. Amen. James 5.16 says, The prayer of a righteous person is very powerful, and so is the Hail Mary, in which we honor the mother of Jesus and ask her to pray and intercede for us. And so we always pray with great confidence from the chaplet of Divine Mercy.
