1 Corinthians 15:21-22

You see, it’s like this. God said that everyone that does bad things has to die. Remember the first man, called Adam. He did something bad, so he died. And we are all from Adam, so we are all in his family, and we all do bad things too, so we all have to die. But then another man came, and he only did good things. That man is Jesus Christ. So now, after people die, God can make them alive again. You see, everyone that believes in Jesus Christ is in Jesus’s family now, so God will make them alive again.
