He built his own Gods from wood and stone and worshiped them. They became worthy of death as punishment. There is a flaw in the moral makeup of man that causes men and women to fall away from God. We are called to obey God. Our old self is now dead, and we are saved from sin.
Christians can t continue in a life of sin with a guiltless attitude.
God can choose whom he will, and He chose the Jews, and has not rejected them ultimately for they will too be saved, but for now, God has grafted the Gentiles in to the Jewish root stock. So you can know and do God s will.
