Today, too many secondary issues, especially on how best to apply Christian morality and truth to the public square, have been made primary. Now hear me clearly, secondary issues are important, and we should debate them. Those ideas have consequences and victims, too. But we are far too quick to make secondary issues primary and to dismiss those on the other side of us as being evil.
Christians should realize that the awe that overwhelms humans when watching man set foot on the moon or a robot land on Mars or astronauts boarding the space station is more than a mere feeling. Rather, it’s a testament to our unique status and role in creation, as well as our drive and capacity to imagine beyond the constraints of what is to what might be, and it’s a reminder that the universe is a place to be known, explored, and even subdued.
The sad fact is that today, starting a conversation with “the Bible says” will often cause the listener to stop listening. So what you do is make arguments based on what the Reformers called common grace, or what historically has been known as natural law. This is what Paul did when he gave his famous sermon at Mars Hill, his first foray into the Greek culture.
