We can sin in so many ways, but none as easily, and completely as by the sins of our flesh. These sins are so natural to us, and fit closely with similar inclinations that we have received as gifts from God. It is in this way that we can find ourselves fooled by Satan, and caught up in them. The desire to make love to your spouse is a close cousin to your sinful desire to commit adultery. The need to protect your family isn’t too far removed from such things as jealousy, fits of anger, or even murder. We walk a fine line when it comes to our flesh, and that line is no broader than the width of our faith.
