1 O thou that hear'st when sinners cry,
though all my crimes before thee lie,
behold them not with angry look,
but blot their memory from thy book.
2 Create my nature pure within,
and form my soul averse to sin;
let thy good Spirit ne'er depart,
nor hide thy presence from my heart.
3 I cannot live without thy light,
cast out and banish from thy sight;
thy holy joys, my God, restore,
and guard me, that I fall no more.
4 A broken heart, my God, my King,
is all the sacrifice I bring;
the God of grace will ne'er despise
a broken heart for sacrifice.
5 My soul lies humbled in the dust,
and owns thy dreadful sentence just:
look down, O Lord, with pitying eye,
and save the soul condemned to die.
6 Then will I teach the world thy ways;
sinners shall learn thy sov'reign grace;
I'll lead them to my Savior's blood,
and they shall praise a pard'ning God.

O Thou that hear'st when sinners cry. I. Watts. [Psalms li.] This is the third part of his L.M. version of Psalm li. It appeared in his Psalms of David, &c, 1719, p. 143, in 8 stanzas of 4 lines, headed "The Backslider restored; or, Repentance and Faith in the Blood of Christ." In its full form its use is limited, but the cento therefrom beginning with stanza v., "A broken heart, my God, my King," is found in a large number of hymn-books. A second cento beginning with stanza iv. is in the American Methodist Episcopal Hymns 1849, as "Though I have grieved Thy Spirit, Lord."
