What diff'rent powers of grace and sin

What diff'rent powers of grace and sin
Attend our mortal state
I hate the thoughts that work within,
And do the works I hate.

Now I complain, and groan, and die,
While sin and Satan reign;
Now raise my songs of triumph high,
For grace prevails again.

So darkness struggles with the light
Till perfect day arise;
Water and fire maintain the fight,
Until the weaker dies.

Thus will the flesh and spirit strive,
And vex and break my peace;
But I shall quit this mortal life,
And sin for ever cease.
