Why is "In God We Trust" on all U.S. Coins and Currency?

If God is important enough for the United States of America to proclaim its trust in God on all U.S. currency and coins, then shouldn't we consider making God an important part of our lives?

A Brief History

America was founded on Christian principles. The United States of America decided it was important to proclaim its trust in God on currencies, buildings, documents and in songs and speeches.

"In God We Trust" became the national motto of the U.S. in 1956. The term first appeared on a two cent coin in 1864. The first reference to the motto is thought to have come from the U.S. National Anthem - The Star-Spangled Banner.

Some Bible refererences to trusting in "God" or the "Lord": Psalm 2, Psalm 20, Psalm 37, Psalm 56, Psalm 62,  Proverbs 3:5, Proverbs 22 and John 14.

On July 11, 1954 the U.S. Congress enacted Public Law 84-140 requiring all U.S. coins and currency to have the motto "In God We Trust".
