 If you dont do the things that Jesus says, it is no good to say that you believe in him. If you dont know much, and if you want to argue with me, just think about the story of Abraham, our grand-father that lived a long time ago. God told Abraham to give him his son Isaac. To do that, Abraham had to kill Isaac, and burn his body on a table made of stones. Abraham believed that somehow God would make it end up all right, so he started to do that hard thing that God said. He was going to kill Isaac. But just then, God told him to stop. You see, God says this in his book, Abraham believed what God said, so God was really happy with him, and told him, You believe me, so now Im saying you are properly good, like you never did anything wrong. And that is how it happened. In another place it says that Abraham not only believed God, but he also did that hard thing God told him to do, so Abraham was a friend of God.
