Okay kiddo, have you ever heard of something called baptism? It's when people get water poured on their heads to show that they believe in Jesus and want to follow him. But what about people who may not have had a chance to get baptized before they died, do they get to go to Heaven? Well, some people think that if a person really wanted to be baptized, but couldn't for some reason, then God will still let them into Heaven. This is called "baptism of desire." It means that even if someone didn't get baptized with water, if they had a strong desire in their heart to be baptized, then God will accept that and let them into Heaven. It's like God knows what's in our hearts, and as long as we truly want to follow Jesus, that's what really matters.
