Could I save the world?

When I look at my son, when I look deep in his eyes
and I see the true child, the love, the surprise
could I sacrifice him, knowing if I don't the world dies
Knowing, even knowing, that again he would rise

Even if I knew I'd see him come day three
If it were certain, for sure, a true guarantee
and on the day he returned, mankind would be free
could I watch him get humiliated, for all to see

Could I watch him carry his cross, and not offer a hand
Watch him drag it, weak and bloody, across the land
without screaming "That's enough!" and drawing a line in the sand
Could I watch him fall down, and not make a stand

Could I watch him get whipped, and thorns pressed to his head
Could I look him in his eyes as he cried, as he bled
Could I allow this, even though I knew he'd rise from the dead
No, man I couldn't, I'd ask that I die instead

But if it didn't work because I wasn't the one
and if I wasn't good enough to save everyone
If no matter how I tried, I couldn't save anyone
Then the world would have to die, because I could not give up my son

I could not let him go, I could not say good-bye
I could not bear to see a painful look in his eye
Without my son, every day, I could only lay and cry
My son is my life, so I guess the world would die
