The Scripture index in our hymnal had absolutly nothing for that part of Job (much easier would have been if we were covering Job 19 -- "I know that my redeemer lives..."). So I just went with hymns mentioning suffering, sickness, trials, and temptations, and trusting God in the midst of same.
122 - All glory be to God on high
573 - What a friend we have in Jesus (I accidentally told the pianist the wrong number, the version with the unfamiliar tune; we'll see if she can sight read #574instead)
131 - When in the hour of deepest need
439 - I want Jesus to walk with me
585 - In your sickness
586 - Cast thy burden upon the Lord
580 - My life flows on
Rosie, What hymnal are you using?
I know it has been mentioned in the past, but it would be nice if LOGOS had a hymnal index. There are a number of hymn resources, but a somewhat comprehensive index - keyed to hymnals would be nice. I know there are some on the web, but they are not integrated into LOGOS. Since we use the United Methodist Hymnal, I make regular use of "hymnsite.com"; but there are others.
