There have been numerous messiah figures throughout history, but only Jesus was the Son of God who came to seek and save the lost and provide the way to eternal life with His Father in Heaven.
When Christians call the Savior “Jesus Christ,” they are really saying “Jesus the Messiah” or “Jesus the Anointed One.” Christ is not His last name! Christ is His title, meaning He was sent by God, divinely appointed, to be the Deliverer and King of His people.
