Okay kiddo, let's talk about Isaiah 56. It's a chapter in a book called the Bible. This chapter talks about something called "inclusion" which means making sure everyone is included and not left out.
In this chapter, there are some rules that God has for people to follow. God wants everyone to be able to come and worship him, no matter who they are or where they come from. He says that even people who might feel like they don't belong - like foreigners or people who are different from others - can come and worship him.
God also talks about something called "justice." That means treating everyone fairly and doing what is right. He wants people to be fair and honest, and to make sure that everyone is taken care of.
Overall, the message in this chapter is that everyone is welcome to worship God and everyone should be treated fairly. It's important to be kind to others and embrace our differences.
