“(And the Lord shall be King over all the earth; and on that day there shall be one Lord, and his name shall be the one name.)”
God’s Name is the One Name.
“Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.” (Acts 4:12, KJV)
Jesus is not a separate entity from God. He has the same Name for there is only ONE NAME. God is “King over all the earth” and He is the “one Lord.” “His Name [is] the One Name.” His is the only “Name under heaven given among men, whereby we must be saved.” There is no other. There is only One.
