Doing Good and Being Good 
"...pure religion is 'doing good' and 'being good.' Mormonism may be summarized in those four words. When we do good, it is easier to be good. And when we are good, our hearts are turned to those in need. Second, our happiness and joy are rooted in sacrifice and service to others. As we unselfishly give of our means and our hearts to others and discipline ourselves to sacrifice, we experience lasting joy. Giving blesses both giver and receiver.
My son is on a mission in Oaxaca, Mexico, where the Saints are very, very poor. Nevertheless, they feed the missionaries. Our son is six foot seven, and our food bill was cut in half when he left. It was cheaper to send him than to keep him home. He seemed to eat everything and anything. He and his companion were invited into the home of a woman he referred to as the poorest woman in the ward in Oaxaca.
They sat down to a dinner of beans and tortillas. He wrote to us, 'We ate it all.' She asked if they would like more. As I was reading his letter, I thought, Please, Troy, say no. But he said, 'Yes please.' So she served him the rest of the beans. Then she said, 'I have one very small egg left. Would you like that?' Again, as a father, I thought, Please, say no. But he said, 'Yes, please.' She fried the small egg and cut it in half for those two missionaries and fed them.
Then they started to read the scriptures to express their gratitude for what she had done. She broke down in tears and said, 'Thank you, thank you. I have felt that others who have come to my home did not like my food. Thank you for letting me give to you.'
That is the spirit of the gospel of Jesus Christ, the Spirit of giving that can bless even the poorest widow in Oaxaca, Mexico.
