Galatians 3:24-28

In other words, the law was our guardian leading us to Christ so that we could be made right with God through faith. Now the way of faith has come, and we no longer live under a guardian. You were all baptized into Christ, and so you were all clothed with Christ. This means that you are all children of God through faith in Christ Jesus. In Christ, there is no difference between Jew and Greek, slave and free person, male and female. You are all the same in Christ Jesus.
