While I knew it was scripture from the Bible, I was ignorant as to exactly where it was located and to what it applied (sorry, Grandma). When I got out my Bible and looked it up, the epitaph became even more poignant.
Chapter 14 of the Gospel of Mark is about the plot to kill Jesus. I'm not going to go into full detail. Just know the woman spoke of in verse 8 came and poured perfume on the head of Jesus, and the people around her wondered why she wasted such expensive perfume. Jesus replied in verse 8: "She did what she could. She poured perfume on my body beforehand to prepare for my burial." He goes on to say in verse 9: "I tell you the truth, wherever the gospel is preached throughout the world, what she has done will also be told, in memory of her."
I hope all of that means the life stories and memories of Mrs. Fannie W. Heard live on today.
