Deuteronomy 33:29: How safe, when God hath seal'd

How safe, when God hath seal'd
And hid our life above,
We rest surrounded with the shield
Of His almighty love!
Arm'd with His Spirit's sword,
Which slays the man of sin.
We prove the truth of Jesu's word,
Redeem'd and saved within:

Flesh, earth, and Satan join'd,
Cry out, it cannot be!
But them we soon shall liars find,
From sin entirely free:
Through the great strength of God
We trust to tread them down.
And triumph o'er our foes destroy'd.
And take the starry crown.
