Why is the name of Jesus important for Christians?

The name of Jesus signifies the fulfillment of God's promise for salvation, as noted in Matthew 1:21, where it says He will save His people from their sins. For Christians, this name is a source of identity and assurance, as we are called not only by His name but are also saved by it. In Philippians 2:10-11, we see that every knee shall bow and every tongue confess that Jesus Christ is Lord. This displays the magnitude of His authority and the reverence due to Him, signifying that His name is the ultimate hope and foundation for believers.
