What does it mean that Jesus has the name above all names?

from the old testament

• The Old Testament emphasizes that God’s name represents His character, authority, and presence. In Exodus 3:14-15: God reveals Himself to Moses as “I AM WHO I AM”, establishing His eternal authority and divine identity.
• God declared He will not give His glory to another, showing the sanctity and supremacy of His name (Isaiah 42:8).
• The prophets foretell a coming figure who will be given dominion, honor, and a name above all others (Isaiah 9:6; Daniel 7:13-14).
• The Lord declared that His king, His anointed one, will inherit authority over the nations, indicating the power and honor associated with God’s chosen name (Psalm 2:7-12), which Jesus fulfilled.

from the new testament

• Jesus said, "All authority in heaven and on earth has been given to Me" (Matthew 28:18). This is a comprehensive declaration of authority, encompassing both the spiritual realm ("in heaven") and the physical realm ("on earth").
• Jesus said, “I am the way and the truth and the life. No one comes to the Father except through Me" (John 14:6). As our great High Priest, Jesus is the only one through Whom we can dwell with God for eternity.
• Revelation 19:16 says, "On his robe and on his thigh he has a name written, King of kings and Lord of lords." This title affirms the supreme sovereignty of Christ over all earthly and heavenly rulers.

implications for today

Philippians 2:10-11 says: "so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father." Paul includes those in heaven, on earth, and under the earth—all heavenly, earthly, and demonic beings will bow before and acknowledge Jesus Christ as Lord of all. Jesus is Lord over all the universe and all living beings, whether they choose to serve Him as their own Lord or not (Isaiah 45:23-24). He is the risen one, the Savior, our Lord. He is forever exalted above all. He has the name above all names.

Believers should not take this lightly. We must never use Jesus’ name in an unworthy way—e.g., as part of an expletive. And that isn’t about some magic formula in a word. It’s acknowledgment of Jesus’ status as Lord. So when a comedian starts joking about Jesus, turn the channel. When a coworker uses His name unworthily, don’t laugh or join the conversation. In fact, when we can, we should try to witness to those whose unworthy use of our Lord’s name shows they are lost. One day they will stand before the very One whose name they are misusing. We should warn them before it’s too late.
