Luke 1:47 - Wesley's Explanatory Notes

My spirit hath rejoiced in God my Saviour — She seems to turn her thoughts here to Christ himself, who was to be born of her, as the angel had told her, he should be the Son of the Highest, whose name should be Jesus, the Saviour. And she rejoiced in hope of salvation through faith in him, which is a blessing common to all true believers, more than in being his mother after the flesh, which was an honour peculiar to her. And certainly she had the same reason to rejoice in God her Saviour hat we have: because he had regarded the low estate of his handmaid, in like manner as he regarded our low estate; and vouchsafed to come and save her and us, when we were reduced to the lowest estate of sin and misery.
