How does John Irving use imagery in A Prayer for Owen Meany?

Imagery:

When we held Owen Meany above our heads, when we passed him back and forth—so effortlessly—we believed that Owen weighed nothing at all. We did not realize that there were forces beyond our play. Now I know they were the forces that contributed to our illusion of Owen’s weightlessness; they were the forces we didn’t have the faith to feel, they were the forces we failed to believe in—and they were also lifting up Owen Meany, taking him out of our hands.
