If you have ever been to a shooting range, you know there is a clearly marked line observers are required to stay behind. When the range is "live", the line cannot be crossed for any reason... for obvious reasons. If you cross the line or venture beyond it, you can end up in the line of fire.
Unfortunately, all sin risks aren't quite as evident. A little carelessness can cause a lot of harm. Even a simple oversight can end in disaster. We don't always have the luxury of knowing what is behind each turn, but we aren't really flying blind. We have access to God's guidance through the Holy Spirit to lead us safely away from harm. We just have to be humble and attentive enough to be led His way and strong enough to not follow our own.
