Most people erroneously understand that the word “LORD” and “God” refers exclusively to the Father, while the word “Lord” refers to the Son. However, the Bible uses all three of these words to refer to both Father and Jesus Christ. In fact, the words “LORD” and “Lord” have the same context in the New Testament.
Take Psalms 86 for instance:
1. Bow down thine ear, O LORD, hear me: for I am poor and needy. 2. Preserve my soul; for I am holy: O thou my God, save thy servant that trusteth in thee. 3. Be merciful unto me, O Lord: for I cry unto thee daily.
In Hebrew, these words are translated as follows:
LORD - Yahweh
Lord - Adonai
God - Elohim
However, in the original New testament (Greek), the translation is:
In the Septuagint (Old testament in Greek), the same word “Kurios” is used to mean both “LORD” and “Lord”.
Now, we read in John 20:28, that Thomas said unto Jesus, “My Lord and my God”, meaning “My Kurios and my Theos”. Again, in Rev 4:8 it says the One seated on the throne is the “Lord God Almighty”, meaning “Kurios ho Theos ho pantokrator”.
Rev 19:16 refers to Jesus Christ as “KING OF KINGS AND LORD OF LORDS”.
It is to be noted that there is no variation (LORD and Lord) in the New testament. The same word (Kurios) used for “Yahweh” in the Old testament is used when referring to the “Lord” Jesus Christ.
