For me, it was a reminder of God's love. So many children have stories of parents' divorcing, and be abandoned by one or the other parent, but yet these kids had a wonderful time praising God and enjoying their time at camp. It was a reminder to me, of how humble I need to be before God and other people.
It's so easy for me to think of reasons why I'm better than somebody else, and that makes me feel good about myself. But Jesus challenges us, the Gospel challenges us, the Bible challenges us, to be humble. In Matthew 18, Jesus forgets what is socially acceptable and interacts with a child. He then tells all of the "important" adults that this is God's chosen. Jesus chooses NOT the biggest, NOT the strongest, NOT the smartest, NOT the highest class; but Jesus chooses the little, innocent child, and says that this is who I choose to be in my kingdom. This is who I choose to participate in a new way of living that is marked by self-giving love to others, instead of love of self taking-from-others.
God makes this point in other places, like the annointing of David in 1 Samuel 16. God tells Samuel to annoint, not the first-born, not the biggest, and not the strongest, but the smallest and youngest...little David.
This is a reminder to me, that if I try to look at my own accomplishments, and how I am "better" than other people to feel good about myself, then I'm missing out on the kingdom of heaven. Rather, what reading these scriptures, and ministering among kids at church camp has reminded me is that I am nothing without God's sustaining, redeeming love. And at my worst and weakest, God can make me good and strong--not to be better than or dominate other people, but in order to love people as God has loved me.
Our example of love is Jesus Christ, "who, though he was in the form of God, did not regard equality with God as something to be exploited, but emptied himself, taking the form of a slave, being born in human likeness. And being found in human form, he humbled himself and became obedient to the point of death— even death on a cross. Therefore God also highly exalted him and gave him the name that is above every name, so that at the name of Jesus every knee should bend, in heaven and on earth and under the earth, and every tongue should confess that Jesus Christ is Lord, to the glory of God the Father." (Philippians 2:6-11, emphasis mine)
