One day, while attempting to dismantle a particularly difficult section of the fence, I beat my hands up pretty good. My knuckles, covered with cuts and bloody, provided me with a wonderful illustration to share with my friends: Just because something's free doesn't mean it won't cost you something. This is true of my fence, and it's true of our salvation. Philippians 2:12 says, As you have always obeyed - not only in my presence, but now much more in my absence - continue to work out your salvation with fear and trembling.
This fence has been laying in my breezeway for over a year, waiting to be erected. Isn't that how we treat the free gift God's given us sometimes? Let's get to work. Let's build something with what God's given us.
