This song has been on my heart, lately.
Ryan and I have always held that it is the small things that have the potential to lead to big problems in our marriage. So, we try to carefully guard our marriage in the little things. I think, though, that this is true of any area of sin. When you see someone do something and think, "How could you DO that? What were you thinking?" I believe the answer is very simple. Look at the small, everyday, insignificant choices in their life, and they will point to the end result.
Guard your thoughts. Guard your mind. "The journey from your mind to your hands is shorter than you're thinking..." And when you sin, "it's the little feet behind you that are sure to follow..." and suffer.
"Guard your heart above all else, for it determines the course of your life." Prov. 4:23 (NLT)
