Isaac Watts - Psalm 89 part 4

v.19ff
C. M.
Christ's mediatorial kingdom; or, His Divine and human nature

Hear what the Lord in vision said,
And made his mercy known:
"Sinners, behold your help is laid
On my Almighty Son.

"Behold the Man my wisdom chose
Among your mortal race:
His head my holy oil o'erflows,
The Spirit of my grace.

"High shall he reign on David's throne,
My people's better King;
My arm shall beat his rivals down,
And still new subjects bring.

"My truth shall guard him in his way,
With mercy by his side,
While in my name through earth and sea
He shall in triumph ride.

"Me for his Father and his God
He shall for ever own,
Call me his rock, his high abode,
And I'll support my Son.

"My first-born Son arrayed in grace
At my right hand shall sit;
Beneath him angels know their place,
And monarchs at his feet.

"My cov'nant stands for ever fast,
My promises are strong;
Firm as the heav'ns his throne shall last,
His seed endure as long."

Isaac Watts
