I want a principle within

1I want a principle within
Of jealous, godly fear;
I want the first approach to feel,
Of pride or fond desire;
To catch the wandering of my will,
And quench the kindling fire.

2From thee that I no more may part,
No more thy goodness grieve,
The filial awe, the fleshly heart,
The tender conscience, give.
Quick as the apple of an eye,
O God, my conscience make;
Awake my soul when sin is nigh,
And keep it still awake.

3If to the right or left I stray,
That moment, Lord, reprove;
And let me weep my life away
For having grieved thy love.
O may the least omission pain
My well-instructed soul!
And drive me to the blood again
Which makes the wounded whole.
