Psalm 19: Can reason save from passion's power

Can reason save from passion's power,
Or keep us in the' unguarded hour?
The moral sense in conscious man
Or virtue of itself, restrain?
The dread of shame, or grief, or hell,
Can these the tempting lust repel?
Their impotence too well I know,
And sink before my stronger foe.

To save from sin, convinced I own,
The power belongs to Christ alone:
Yet till my sprinkled heart befieves.
No help the bare conviction gives:
No vows the stubborn pulse can bind:
No succour in the means I find,
In tears that ceaseless flow in vain,
Sad fountain of eternal pain.
It must, O Lord, proceed from Thee
The viftue pure that rescues me:
Thou only canst a sinner part
From sin, and turn and wash my heart;
The virtue from Thy wounds doth flow,
Which none but true believers know
Who glory in a pardoning God,
And feel redemption in Thy blood.
Fain would I to that fountain fly,
Fain would I on Thy cross rely;
A wretched, weak, entangled thing,
To Thee my last distress I bring;
But nought to move Thy grace I have;
Thy heart must find the cause to save,
Or leave a soul to deathless pain,
For whom Thyself hast died in vain.
If justice stern reject my prayer,
My righteous doom in hell I bear;
If mercy graciously forgive.
Pardon I in the dust receive;
The pardon brings preserving power,
It bids me go, and sin no more;
The joy my strength and safety is,
And ripens into glorious bliss.
Believing now in Jesu's name,
Kept by the power of God I am;
Untorn amidst the lions' teeth,
Immortal in the jaws of death;
Superior o'er the floods I ride,
Unburn'd I in the flames abide.
Till Jesus on the clouds comes down,
And brings Himself, the victor's crown.
