The latest mass shooting took the lives of 26 people worshipping in a small Texas church. Now, people are asking what was the caused it? Was it mental illness? Lax gun laws? Was it what some call America's "gun culture?" Alexander Solzhenitsyn reminds us that "evil passes not through states, nor between classes, nor between political parties either – but right through every human heart." It's easy to blame objects like guns and high capacity magazines. But we fail to acknowledge the broken human condition and the reality that sin lurks in the heart of every one of us. Until we understand our nature and the terminal condition called sin, we're missing the root cause of not just mass gun violence, but the root cause of every kind of violence.
