I'm sure you know that the phrase "IN GOD WE TRUST" is written on American coins. But perhaps you aren't aware that God is also mentioned on Canadian coins. Next to the Queen's image the words "D. G. REGINA" can be found. This is a Latin phrase. The letters "D. G." stand for dei gratia. Dei gratia regina means "Queen by the grace of God."
I think it's ironic that American and Canadian coins both mention God. Why? Because North American society does not trust in God; it trusts in money. The recent Canadian election campaign demonstrated this. I don't recall any of the candidates talking about God. But they talked nonstop about money (lowering taxes, creating jobs, reducing the national debt). If we were honest, our money would say, "In God we do not trust."
If our trust is in temporary riches, our joy will be temporary. But if our trust is in the eternal God, our joy will be eternal. Jesus said, "Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also" (Matthew 6:19-21).
