Believing In God?

.
Believing In God? ~ For me, this is easy coz it just makes a lot of sense.

Believing In Which Religion? ~ For me, this one very difficult & a LOT more difficult for those who don't believe.

I heard a priest say this in one of the Movies of Mary's apparition when a non-believer asked why the people were flocking to see Mary.

For those who believe,
No proof is necessary;
For those who do NOT believe
No amount of proof is enough.
