Deuteronomy: Moses, when dead, himself survives

Moses, when dead, himself survives.
He always in his precepts lives;
Though sinners dream his office o'er,
He loses nothing of his power.
His sight is as the eagle's strong,
And Sinai thunders in his tongue.

Think not the law through faith made void,
Its vigour cannot be destroy'd:
It marks our hearts with quickest eye,
And doth our smallest faults espy,
It seizes with almighty hands,
And holds us in eternal bands.

It holds us, when by grace set free
From curse, and fear, and penalty;
The easy yoke of Christ we prove,
Bound to obey the God we love;
And when these heavens are pass'd away.
We still shall glory to obey.
