The lyrics say that if everyone loved, cared, didn’t lie, and shared, then nobody would die. Essentially, if we became selfless we would find a way to all get along, prolong life and rise to the next level for humanity.
In Christian circles we have a tendency to point out flaws in this world view. A world where everyone loves each other and gets along and thinks of their neighbor before themselves is not realistic. Christians rightly point out that while we live in a sin infected world, this ideal will not come to pass. They also feel it is a gross waste of time to pursue social justice over the spreading the gospel.
I understand that, however, we are missing a great opportunity. Rather than pointing out flaws in this world view we should recognize that this song really illustrates well the desires that God put in our hearts.
I believe that we are created in the image of God. God has a plan for man that is actually outlined well in Nickleback's song. If we accept Christ, there will be a world where no death exists, or disease, or selfishness. This perfect sinless world will be ruled by love. As humans our hearts resonate with that. God designed us to look for that. But when people look for that, sometimes as Christians we make fun of them or push them away and they go search for that somewhere else. You can watch how people desperately try and create a perfect world through politics, religion, and social programs. Even in thier personal relationships everything is about love, acceptance, tolerance, and equality. They persue a noble ideal so hard only to wake up and live another day in a sin infected environment. They are hurting and need Jesus.
We need to offer hope, use the current mantra and ideals of our day to point people to God rather than tell them where they are flawed. To a culture brought up in broken homes, disappointments, and marketing campaigns, authentic unconditional love is the most satisfying thing for their aching heart.
Don't belittle, be expedient
If everyone cared and nobody cried
If everyone loved and nobody lied
If everyone shared and swallowed their pride
Then we'd see the day when nobody died
