I want a principle

Hymn (C.M.D.) by Charles Wesley (1707-1788):

1. I want a principle within
of watchful, godly fear,
a sensibility of sin,
a pain to feel it near.
I want the first approach to feel
of pride or wrong desire,
to catch the wandering of my will,
and quench the kindling fire.

2. From thee that I no more may stray,
no more thy goodness grieve,
grant me the filial awe, I pray,
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.

3. Almighty God of truth and love,
to me thy power impart;
the mountain from my soul remove,
the hardness from my heart.
O may the least omission pain
my reawakened soul,
and drive me to that blood again,
which makes the wounded whole.
