 1 Corinthians 12.3, Romans 10.9. And Lord refers to God. Once again, the divinity of Christ. This comes from Exodus 3, the burning bush incident. And Moses is like, well, if I go to Pharaoh and say, let my people go, who am I going to tell them sent me? Who are you? Who are you, Lord? And God says to him, I am that I am, or I am who I am, the one who is God.
