Some Children, after hearing President Monson say this, started a "warm fuzzies jar". Each time they did something good for another person they were able to put a warm fuzzy in the jar. They kept going until the jar was full.
This year in our Primary, we are doing the same. Each week, children as assigned to report on their experiences of "doing good."
As a result, today Ella shared this thought in Primary:
"I sing in the International Children's Choir. A few weeks ago, I was able to perform at the Church Office Building for a number of delegates from around the world. As we entered, we saw a table full of Book of Mormons in each of the native languages of the delegates. I hope that my gift of song will plant a desire for each delegate to read the Book of Mormon, and know of the happiness that the gospel brings."
