It is a wonderful bible promise. If you do, be sure to pray for the hungry and sick children that are in the world. It is also a good thing to give some money or do work to help other people. Jesus loves little children very much. Most of the things I talk about on this page are things you can learn about in Sunday School.
Some churches do it different though.
Some children ride a bus to Sunday school. Jesus walked on this earth 2,000 years ago. I think it is really neat that all the time starts at the cross. It is not saying that our Lord died, but that He still lives among us through His spirit, The Holy Spirit that The Father sent to us when Jesus went to heaven. When you are feeling sad or alone, if you ask God to be with you, He will send you the Comforter and make everything feel better.
