Do “Lord” and “GOD” mean the same thing?
"LORD" (Hebrew: adonai) stands for the name of GOD: Yahweh. The title "Lord" (Hebrew: adon / ancient Greek: kyrios) is used for both GOD and earthly rulers, kings, rulers, landowners, landlords, slave owners, fathers and husbands. "The LORD" (adonai) made Jesus "Lord" (adon) over all creation and head over the church of GOD (Acts 2,36 / Ephesians 1,22). Jesus Christ came in the name of the LORD / Yahweh. He is both "the" (Old Greek: ho) Lord and "our" (Old Greek: hemon) Lord, which underlines that Lord is a royal title. However, nowhere does it say that GOD is “our” LORD / Yahweh. "Lord" (kyrios) and "GOD" (Old Greek: theos) do not fundamentally have the same meaning. Rather, it depends on the respective context.
