We loved it when children would come to our display table and ask us all about Brazil and what it's like to be a missionary.
We also tried to show the kids that there isn't anything extra-special about us. We are simply common, ordinary people who are allowing God to use us to reach people in Brazil.
I know that missionary presentations had a big impact on me as a young person, and we trust that the Lord was able to use us to impact others as well.
