A few years ago while visiting India, I took a trip in a taxi. The driver, who was Hindu, had statues and images of Buddha and several other “gods” attached to the car’s dash. After I revealed myself as a Christian, the driver made sure to show me his small image of baby Jesus in a manger. He was intent on covering all his bases when it came to worship.
The first commandment taught us who God is. The focus is on His exclusivity. The second commandment taught us how to worship the One and Only.
