XRISTOS is Greek for Christ, the Messiah Jesus.
Luke 2:11 For unto you is born this day in the city of David a Savior, which is Christ the Lord.
The term Christ is more of His title or descriptor than His name as we see in Peter’s revelation:
Matthew 16:16 And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
And again referenced by the woman at the well:
John 4:42 And said unto the woman, Now we believe, not because of thy saying: for we have heard him ourselves, and know that this is indeed the Christ, the Savior of the world.
Jesus is the Christ, the Savior of the world and my Savior. The relationship is personal and must be personally embraced. Make certain you have this relationship. Then you can say boldly with Paul:
Romans 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
…and for you.
