Our life experience has taught us that there are consequences to our actions. There are both positive consequences and there are negative consequences. We would love to live in a world where we would only experience the joy of the positive consequences while being insulated from the negative consequences of our choices. I would would love to be able to eat whatever I want and enjoy the taste of good food and not have to deal with the negative consequences of heartburn and weight gain. Choice always involves consequences.
There is a part of me that wonders why God doesn't save us from consequences of bad choices. Let's face it our lives are vastly more complicated because of bad choices that were made, not only by ourselves, but also by other people. We are not immuned from the "bitter fruit" of unwise living. Part of the explanation for that is found here in Proverbs chapter, we need experience the full terror of the path that has been chosen. That is the only way that we will come to realize that there is a better way to live, that the world is not what it should be, and that there is hope.
While we live in this world there is no escaping the "bitter fruit" of poor choices and unwise living, but there is a way to live with hope. That requires us to follow Jesus and fight against that bitter fruit. We seek to rescue people out of the darkness, to bring healing to their lives, and to help them discover the hope that is in Christ Jesus. The bitter fruit doesn't have to be our main course, instead we can discover the delicious fruit of a Spirit led life, and that will make all the difference in our lives.
