God Says, I'm Going to Give You a New Covenant

God says, i'm going to give you a new covenant. No matter how much you mess up, to day, new mercies for to morrow. God's all about the new. He likes making things that are awsome, even better than they were. But why does god yo to crate a ne w heaven? What's rong with heaven? Heaven seems to me like it's in perfect condition. So that tells me that god doesosn't make new things because the old thing needs to be new.
