Maybe you mean this one (Calling Now by Philip Bliss):

This loving Savior
Stands patiently;
Tho' oft rejected,
Calls again for thee.

Refrain

Calling now for thee, prodigal,
Calling now for thee;
Thou hast wandered far away,
But He's calling now for thee.

Oh, boundless mercy,
Free, free to all!
Say, child of error,
Heed the tender call.

Refrain

Tho' all unworthy,
Come, now, come home-
Say, while He's waiting,
"Jesus, dear, I come."

Is it this one:

Lyrics and Music: Lewis Hartsough

I hear Thy welcome voice
That calls me, Lord, to Thee,
For cleansing in Thy precious blood
That flowed on Calvary.

Refrain:
I am coming, Lord,
Coming now to Thee:
Wash me, cleanse me in the blood
That flowed on Calvary.

Though coming weak and vile,
Thou dost my strength assure;
Thou dost my vileness fully cleanse,
Till spotless all and pure.

'Tis Jesus calls me on
To perfect faith and love,
To perfect hope and peace and trust,
For earth and heav'n above.

The chorus of an old hymn begins with "Calling now for thee"; can you help me find the title?

Thanks, and thanks for your great website,
