Mary needed Jesus, God the Son, as her Saviour too and she acknowledged that God was her Saviour:
46 And Mary said, My soul doth magnify the Lord,
47 And my spirit hath rejoiced in God my Saviour.
Only a sinner needs a Saviour and all of us do!
For all have sinned, and come short of the glory of God.
Jesus is the Saviour of the world - the ONLY Saviour!
Neither is there salvation in any other: for there is none other name
under heaven given among men, whereby we must be saved.
Evangelist Alex Bowler
