Genocide in Rawanda

I just watched an interview of Immaculee, a Rowandan survivor of the 1994 genocide, where she tells her story of not only surviving a terrible massacre but how she turned to her Catholic faith and overcame the anger and hatred she felt for the ones responsible for the death of her people.
She spoke of praying the sorrowful mysteries and the chaplet of mercy from the time she awoke to the time she fell asleep each day -- for 91 days! She spoke of how our blessed mother healed her heart from the bitterness and anger and instead filled her with God's love and His joy.
She said we are to approach God as if we were beggars imploring Him for our needs. If we do not have the sincerity within to pray, then we are to ask Him for this as well. Please God -- help me to pray with sincerity and with great devotion.
