Afflicted saint, to Christ draw near—
Thy Savior’s gracious promise hear,
His faithful Word declares to thee,
That as thy days thy strength shall be.

Let not thy heart despond and say
How shall I stand the trying day?
He has engaged by firm decree,
That as thy days thy strength shall be.

Thy faith is weak, thy foes are strong,
And if the conflict should be long,
The Lord will make the tempter flee,
For as thy days thy strength shall be.

Should persecution rage and flame,
Still trust in thy Redeemer’s name;
In fiery trials thou shalt see,
That as thy days thy strength shall be.

When called to bear thy weighty cross,
Or sore affliction, pain, or loss,
Or deep distress or poverty,
Still as thy days thy strength shall be.
