The Change from Law to Faith in Christ - Graham Anns - 7th June 2015

What is the difference between living under the Law and living by faith?  Why does this passage talk about going back to slavery and how is it relevant to us living in the Western world today? What is the difference between striving to keep rules and what we call sanctification?  Graham Anns speaks on Galatians 3 vs 23- 4 vs 7.
