I know not why my Sav­ior
Has done so much for me;
I know not why His fa­vor
Has come so con­stant­ly;
But this I know: I love Him
And trust Him day by day,
And cast my care upon Him,
And watch and praise and pray.

I know not why my Sav­ior
Should leave a glo­ri­ous throne
To bleed and die on Cal­va­ry,
For sin­ners to atone;
But this I know, ’tis cer­tain,
He ful­ly ran­somed me,
And in that truth be­liev­ing
I realize I’m free.

I know not why He bids me
Breathe forth my wants in pray­er,
While day by day He sees me,
And knows my ev­ery care;
But this I know, while pray­ing
And trust­ing in His Word,
My soul re­freshed and strength­ened,
Rests sweet­ly on the Lord.

I know not where He leads me,
And yet I fol­low still;
I know not why He needs me
My vine­yard place to fill:
But this I know, at du­ty
In pray­er or ho­ly song,
My heart keeps ov­er­flow­ing
With rap­ture all day long!
