What I know not teach Thou me:
To my op­ened eyes un­fold
More than mor­tal sense can see—
More than mor­tal heart can hold—
Show me Christ on Cal­va­ry.

What I know not teach Thou me:
Show me all my hid­den sin;
Break its pow­er, and set me free.
Pure with­out and pure with­in
Let Thy ran­somed ser­vant be.

What I know not teach Thou me:
In Thy vine­yard choose my place.
Make me wise thy choice to see.
Give me skill in ways of grace,
Leading ma­ny souls to Thee.

What I know not teach Thou me:
On those heights which saints have trod
In their mas­ter’s com­pa­ny,
Lead me in the light of God;
Let Thy ser­vant walk with Thee.

What I know not teach Thou me:
Check me where I cross Thy will.
As my fad­ing vi­sions flee,
Bid my thwart­ed heart be still,
And, re­joic­ing, wait on Thee.

What I know not teach Thou me:
When with tan­gled feet I stand,
Held by toils I can­not see,
Let me keep Thy guid­ing hand;
Step by step my lead­er be.

What I know not teach Thou me:
When I seem for­sak­en quite,
And my fears rise like the sea,
Let me feel Thine arm of might
Fold me in its pa­no­ply.

What I know not teach Thou me:
When my dark­est hour shall come,
Whilst I wait and watch for Thee,
Lift the veil and take me home;
Let Thy child Thy glo­ry see!
