Okay kiddo, let's talk about Isaiah 49. This is a part of the Bible that talks about a person named Isaiah who was talking to God. Isaiah was telling us about a special servant that God had chosen to do important work for Him. The servant was going to help people and show them how to be good.
Now, God had plans for this servant even before he was born. God knew he was going to be important and do great things. The servant was a bit nervous about his job, but God reassured him that He would be with him every step of the way.
As the servant went about his work, some people didn't believe in him and made fun of him. But the servant didn't give up, and he kept doing what God called him to do. Eventually, many people started believing in him and realized that God had sent him to help them.
Isaiah wanted to make sure that people remembered this servant and all the good he did. So, he wrote down everything about him in the book of Isaiah, so that people could read it and learn about him.
So, in short, Isaiah 49 is a part of the Bible that talks about a special servant that God chose to do important work, and he did it with God's help even when some people didn't believe in him. And his story was written down so that we can remember him and learn from his example.
