I'm afraid that the more I say about this song, the less meaningful my comments will become. Let me just point out the two most powerful moments in the music video.
I will Make you Hurt (2:35-2:40)
When June (Cash's wife) looks down at him from the stairs, it's a look that says a thousand words. When I see that expression on her face, it's like I can feel it too. It's like she lets out a big sigh that says, "It pains me so much to hear you say all this - but I love you. I love you too much to reach out and make you stop. I'm going to let you journey down this path of healing and redemption. And as you do, I'll be here for you. Waiting. Ready to love you, no matter what."
My Empire of Dirt (2:53-3:09)
If you didn't react in some way physically (sit up in your chair, grunt in surprise, raise your eyebrows, put your hand over your mouth, ANYTHING) when Cash started pouring out that wine - you better call an ambulance because you're a dead man walking. Notice the priceless stare down from Cash as his shaky hand pours out the contents of his glass. That wine spills all over the place and we can see the utter disgust of a man determined to abandon everything he once held as valuable.
What Have I Become?
That question, "What have I become?" is the most applicable. To me, performing an internal inventory can be purging and damning at the same time. As we look back at where we've gone wrong, we can confess it before God, and ask for forgiveness - and this purges us of our sins. However, when we take an honest look, not at our gross sins, but at our subtle ones; not at our actions, but at our motives - it is damning.
But God's grace is greater than all our sin. When we approach Him through Jesus Christ, we unlock the floodgates of God's infinite mercy with the key of faith.
