Hymn Lyrics Search - Name That Hymn

I really don't know this song,or the title, All I have is some lyrics and this might be the chorus( God's precious Holy Word,Don't change it,just leave it alone.) and this is a verse of it.( Each word and each line tell his goodness devine) Don't change it,just leave it alone. My father-in -law sang this long ago.
Thank You for any help!
