I am not skilled to understand

While this song has been in the Believer's Hymn Book (#251) originally written by Dorothy Greenwell- 1873, I have never heard it sung before. However, this song has been on the radio frequently on my trips to and from school. Leaving all of the music aside, the lyrics have been particularly significant to me.
The song begins:

I am not skilled to understand

What God has willed, what God has planned

I only know at His right hand

Stands one who is my Savior

I take Him at His word and deed

"Christ died for sinners"; this I read

And in my heart I find a need

Of Him to be my Savior
