If ever there were a more drastic comparison between the two religions, this is it. One is of love and forgiveness. One is of hatred and murder.
That's why what Sr. Leonella did (I'm not speaking of merely dying, but of forgiving those who murdered her) is more powerful than bullets and bombs. Some Islamic person somewhere will hear of this and think, "This is goodness beyond anything that human nature, unassisted, can provide. Where did she get such a power?"
The conversion of the hearts of Muslims. That's what we should be praying and fasting for. I'm sure that's what Sister Leonella is praying for now.
