 Well, in the same way, nobody can change what God promised to Abraham, and to Abrahams son, and to all the people in his family. You know, we can read this story in Gods book. God doesnt say that he promised things to Abrahams sons, like it is talking about a lot of people. No, he is talking about only one man. He says Abrahams son. You see, God promised those things to just one man, and that man is Jesus Christ.
