Psalm 139, Part 3 – Sincerity Professed, and Grace Tried

My God, what inward grief I feel
When impious men transgress thy will!

My God, what inward grief I feel
When impious men transgress thy will!
I mourn to hear their lips profane
Take thy tremendous name in vain.

Does not my soul detest and hate
The sons of malice and deceit?
Those that oppose thy laws and thee,
I count them enemies to me.

Lord, search my soul, try every thought;
Though my own heart accuse me not
Of walking in a false disguise,
I beg the trial of thine eyes.

Doth secret mischief lurk within?
Do I indulge some unknown sin?
O turn my feet whene’er I stray,
And lead me in thy perfect way.

Or, The Heart-Searching God

Isaac Watts
