God, Lord God or Lord?

In class, my group agreed that "God" refered to the God that created everything, from light and dark to creatures and humans. This Gods is seen as distant, somewhat mean. "Lord God" refers to the creator of Eden. He is the one that makes rules, the one that explains to man "how to live". After humans eat from the tree of knowledge of good and evil, and expulsed from Eden, appears the "Lord", a compationate friend to us. We can see the difference between the Lord and the Lord God un the following passage: "[1] After these things the word of the LORD came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward.[2] And Abram said, Lord GOD, what wilt thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus?" After all, The God, the Lord God and the Lord are the same God, but in different points of view. The also describe the different needs of people. At the beginnig, we only needed a creator. As time passed, we started to need a friend, a support, someone who we could talk to, a savior we felt that listened.
