We need others to help us see what is in our blind spots.  We can’t always see the "snake in the grass" (satan) or deal with the "enemy within" (our flesh) by ourselves.

That is why so many have wondered why Adam didn’t help Eve.  After all, the text says that Adam was "with her" (Gen.3.6b) and yet he did nothing.

Why do you think he was silent when Eve needed him most?
