John the Baptist was a great prophet. He taught people to repent. Then he baptized them.
One day John was baptizing people in the river Jordan. Jesus came and asked John to baptize him. John knew that Jesus didn’t have any sins. So why did Jesus want to be baptized?
Jesus said He needed to obey all of the commandments. Being baptized is a commandment.
We can obey the commandments and choose to be baptized, like Jesus. Then we can be confirmed and have the gift of the Holy Ghost too.
