Most of us are pretty good at avoiding problems we see coming. When the jar in the refrigerator has a 2-year-old past due date, we throw it out. When the road sign says danger sharp turn ahead, we slow down. But the most dangerous situations are not announced. They catch us unaware. That’s true physically and spiritually. If you would like to avoid one of the greatest invisible dangers in the Christian life, then you will want to listen in to Kent, Vicki and Nathan as they see the danger that overwhelmed Cain in Genesis 4 and threatens us today.
