But we humans are full of shameful sinfulness. When God first made the world, there was no sin. God walked with Adam in the Garden of Eden. Adam could look at God's face and enjoy being with Him everyday. So did their children when they were born.
Sin is the cause of all the bad troubles and suffering in our world.
Sin is a terrible, terrible thing. Because of our sins we are separated from God. This happened more than three thousand years ago. The man's name was Moses . He was a smart and well-educated man who had almost been killed when he was a baby.
