Let us engage our dear fellow here.
First of all, I don't even know what 'kill soul' means at face value, must less any deeper interpretation. I know that U2 usually plans out their words and presentation carefully, and often times only those who are knowledgable of Christianity get the deeper meaning. That being said, I don't have any idea what the significance of 'kill soul' is.
So most would argue that as Christians, U2 should be bold and direct in their message. They shouldn't be dodgy or obscure in any way. I agree with this sort of thinking in alot of circumstances, but God uses different people in different ways. He may want you and I to be very clear about the plan of salvation when we are conversing with someone, but
He didn't reprimand Jesus when he spoke in parables that his audience didn't understand . Sometimes Jesus explained the parables only to the disciples in private. What good did this kind of preaching do for the masses? I can't say that I understand, but I do have believe that Jesus fulfilled his mission, nonetheless.
So U2 don't take the stage and present the Gospel like Billy Graham. Maybe they are still doing God's work, just in a different way. I'm alot like you in that I pay attention to lyrics, and really appreciate the message in songs like The Playboy Mansion, Until the End of the World, Grace, etc. I like how Bono embedded the Gospel message into Discotheque (it's the Way/ you don't pay/ that's ok/ cause you can't earn it).
Regarding the Coexist thing, I think that Christians should rather see peace in the Middle East than violence. If we don't see peace until the second coming, then so be it. We are still commanded to strive for peace. It seems that you are advocating that we do not communicate AT ALL (surely you're not promoting violence towards Jewish and Muslim people) with people of different faiths. Well, that doesn't accomplish anything. If we understand each other better and communicate, then maybe the truth will have a chance to be conveyed from one to another. So all in all, I'm a supporter of the Coexist message.
Regarding the end of the world, I don't have the schedule for it, but I'd like to think you're right. I'm not so sure how you can be so sure though.
One other thing here (your username is kind of weird
), try to explain yourself a little better. I'm not sure if any of us really understand what you're trying to say. That may sound crazy to you, but it's the truth.
