Our spouses can bring us more joy and strength than any other relationship on earth. I think this was the case with Joseph and Emma. They were driven from town to town, rarely had a home of their own, and suffered mercilessly at the hands of mobs and devils, many times left with little else but each other.
After the death of Joseph, the Saints began to prepare for the trek west. Over the coming years as the saints came through Nauvoo, I could imagine Emma going to the bank of the river and watching them cross.
I can see her watching the endless wagon trains and handcarts bound for the city and faith that Joseph founded. Knowing she was not going west, I can imagine her whispering as she watched them disappear, "Forgive Me, Joseph."
