I love this question.
40
Where The Streets Have No Name
A Sort Of Homecoming
Mothers Of The Disappeared
Hold Me, Thrill Me, Kiss Me, Kill Me
I Still Haven't Found What I'm Looking For
Here's why:
I chose '40' because of its relation to the Psalm and also the ambiguity within the song "I waited patiently for the Lord" and "how long to sing this song" as well as the hopeful, longing message in there as we wait for God, peace, etc. It shows you can ask why but also not give up hope.
Streets: My favorite 'worship' song U2's written. It is such a joyous and spiritual song, with the lights blinding out the band and highlighting the people in the audience who are celebrating. The lyrics are so uplifting and energetic and positive- "I go there with you, it's all I can do" I think this is one God Needs to see live!
A Sort Of Homecoming: Another song that seems to me would strike God. It is not as celebratory as the others because of the slightly mournful feel to it- having to leave and be separated from someone while you ache for them..promising to run to them. It includes a lot of raw human emotion- "just a scream" and "plowed faces" and the need for "build(ing) a bridge". I sort of see it as all the things we have to go through to get to the light in the distance.
MOTD:
It deals with the very real horror many people suffer every day. Just a gorgeous song that I think God could relate to as He has to see this every day, as well, and to hear it you know Bono sympathizes with these people.
HMTMKMKM: On a personal note speaks a lot about Bono's fame and shows his trangressions through his confrontations with it, from JT->Fly->Macphisto. Another song showing they won't give up at 33, and if delved deeply enough it explains their motivations for AB & the music that followed.
ISHF:
Just another staple. Showing God how they're always searchign, looking, will continue to push the gifts they've been given until they get to that "perfect place" They don't take anything for granted & don't want anyone to take them for granted, either.
