"In the final analysis, what's it (life) all about?"

Prager has settled on "doing good for others."

I can't think of a better goal. One of my religious friends once told me something he had heard in a class on his religion: "God put us here on Earth so that we could let him walk on Earth."

Or, in his words, God could walk this earth without a creature here who appreciated him, but what would be the point? We're here to do God's work and to demonstrate His love to one another and to do the work he would ask us to do. We are meant to act as His hands and feet. I would add that failing to do so is abandoning God.
