It was interesting because he also talked about the power we have, the power of modern technology, intellect, etc., and how sometimes it was easy to be prideful, because of these great power we have. So it's even harder sometimes to be truly humble "like children".
I also like to think that children are innocent and pure of heart and full of trust and complete faith. An infant fully and completely trusts in his mother to feed and nurture him; we need to put the same faith and trust in God to feed and nurture us.
God bless.
Amen!
