Isaac Watts - Hymn 60

The Virgin Mary's song.

Luke 1:46ff.

Our souls shall magnify the Lord,
In God the Savior we rejoice:
While we repeat the Virgin's song,
May the same Spirit tune our voice!

[The Highest saw her low estate,
And mighty things his hand hath done:
His overshadowing power and grace
Makes her the mother of his Son.

Let ev'ry nation call her blest,
And endless years prolong her fame;
But God alone must be ador'd:
Holy and reverend is his name.]

To those that fear and trust the Lord,
His mercy stands for ever sure:
From age to age his promise lives,
And the performance is secure.

He spake to Abram and his seed,
In thee shall all the earth be blessed;"
The memory of that ancient word
Lay long in his eternal breast.

But now no more shall Isr'el wait,
No more the Gentiles lie forlorn:
Lo, the desire of nations comes;
Behold, the promised seed is born!

Isaac Watts
