A Family Motto - WHY ?
When living in the U.S.A. for some time I was inspired by the imprint of "In God We Trust" on every greenback and every coin.....
Why did I - as a religious person - not choose: "In God We Believe"?
Because belief finds its fulfillment in trust. A Greenback has a certain "purchasing power" that is undisputed. We don't just believe it, we use it every day, we experience it, thus we trust .......
Once one has experienced God then belief - at least temporarily - has created the bridge to the experience.
If a belief system - and that in my opinion is the ultimate purpose of any religion - brings us in touch - into communion - with God, it is useful and good.
Many experiences with God create trust, thus...... In God We Trust.
