Spirituality

I don't understand why people feel the need to prove their spirituality to other people.

.. by talking about how much they pray or fast.

.. by trying to fit in a Bible reference to every sentence they make.

.. by trying to show openly in worship that God is doing something within them.

Why can't people just sit back and let God work in them without having to show it to other people?

I don't mean sharing what God is doing.... because that's good and I believe that's important.

I know what I mean.
