The world and Christ are enemies. When you come to Christ, you receive certain freedoms. You do not have to be like the world, although you can love them, although I am not encouraging Christians to become non-conformists, either. The world lives by certain normals and morals which Christians are not obligated to follow. A normal means that each person does what each person believes that the world does. A moral is about how the way the world behaves. Christians, you have become free of these when Jesus died on the cross. However, you also have the freedom to do as you ought. You, as a Christian, cannot do as you please. God has expectations for the Christian, as well. And we have to obey the government, also. So, you are free of the world's way of thinking. You are free of the law of sin and death. You have been set free by the Lord, Jesus Christ.
