It has often been pointed out that there are two types of people: there are iPhone people and there are Android people; there are Coke people and Pepsi people; there are iOS people and Windows people. What we are going to see in this passage in Galatians is that the Apostle Paul also says there are two types of people: Ishmael's people and Isaac's people. There are flesh people and there are Spirit people, and there are slave people and there are free people. Paul’s question to the Galatians, and his question to us, is which person are you going to be? Are you going to move back into slavery under the law or are you going to live free in Christ?
