Begin, My Tongue, The Heavenly Theme

Begin, my tongue, the heavenly theme,
Awake, my heart, and sing
The word, unchangeably the same,
Of our eternal king.

Tell of his wondrous faithfulness,
And sound his power abroad;
Sing the sweet promise of his grace,
And the performing god.

Proclaim, "salvation from the lord,
To wretched, dying men:"
His hand hath writ the sacred word
With an immortal pen.

Engraved as in eternal brass,
The mighty promise shines;
Nor can the powers of darkness rase
Those everlasting lines.

Yes, every word of grace is strong
As that which built the skies;
The voice that rolls the stars along
Speaks all the promises.

O, might i hear that heavenly tongue
But whisper, "thou art mine!"
That gracious word should raise my song
To notes almost divine.
