Your worst problem is not your sin. The worst problem is the worldview you have adopted that allows you to think your sinful choice was an appropriate response to the situation at hand.
We too often focus on the acts of sin, which are bad, disgraceful, shameful, and without excuse. But those wicked acts do not exist in a vacuum. They are the product of a worldview that we have adopted.
Addressing the acts alone is like weeding the garden with a lawn mower. It may make it look a little better, but it will not solve the problem.
If we will solve the sin problems of life, we must address them at the root level of our worldview.
