Intro: I am the Lord => God is and who God is
1. Thou shalt have no other Gods => WHO must be worshipped
2. Thou shalt not make unto thee any graven image => HOW he must be worshiped
3. Thou shalt not take the name of the Lord thy God in vain => MANNER of worship
4. Remember the Sabbath day to keep it holy => HOW MUCH/WHEN we worship
It is required that we obey all of the law of God, but there is a beautiful logical priority to the first table going from most essential (intro) to least essential (Sabbath).
