So, you know how when you do something good or bad, your parents might give you a reward or a punishment, right? Well, when we die, God kind of does the same thing!
After we die, we go through something called particular judgment. This is when God looks at all the good things and bad things we did during our life. If we did more good things than bad things, then we get to be with God forever in heaven! But if we did more bad things than good things, then we have to go to a place called hell.
It's kind of like getting a report card from God. If we did really well, we get an A+ and get to go to heaven. But if we did poorly, we get an F and have to go to hell.
So, it's important to try to do good things and be kind to others, so that when we die and go through particular judgment, we can hopefully get a good grade and go to heaven.
