In Martin Luther’s Large Catechism appears an argument demonstrating that everyone is religious whether they intend to be or not. Luther writes:
“What does it mean to have a god? Or, what is God? Answer: A god means that from which we are to expect all good and in which we are to take refuge in al distress. So, to have a God is nothing other than trusting and believing Him with the heart. I have often said that the confidence and faith of the heart alone make both God and an idol. If your faith and trust is right, then your god is also true. On the other hand, if your trust is false and wrong, then you do not have the true God. For these two belong together, faith and God [Hebrews 11:6]. Now, I say that whatever you set your heart on and put your trust in is truly your god.” (Large Catechism I 1—3)
So where ever we place our highest trust, that becomes the object of our religion, our faith. If an Indian in the Amazon forest trusts his totem animal for help and security, then that is the basis of his religion. If a radical environmentalist places his trust in nature, then nature is his god, the object of his devotion. If an ingenious philosopher denies that there is a god but places his trust in the state (as happened under communism), then the state has become his god.
You have a god. Everyone does. So the question becomes: Is your god the true God?
