I am the Lord your God!
It means, I so Speak BECAUSE I am the Lord your God. I do not need to give any reason. I, the Lord, am the reason.
If you See This you will NEVER be able to live by reason any more.
You will say to God: Whereas in the past I lived by thought and reason, now I Bow and Worship You; whatever You have Done, BECAUSE it is You who have Done It, is Sufficient for me.
