At my most recent doctor's appointment, I found out that the little bit of redness that had developed around each of the stitches was actually a sign of infection. The doctor said that I would need two weeks of antibiotics to clear it up. It didn't look that bad to me, but he said it is what was happening on the inside that could be more troublesome.
This whole scenario reminded me of our sin. Sometimes we might notice a bit of "redness" and rationalize that it doesn't look too bad. Our sin can seem insignificant if we judge it merely by outward appearance or when we compare it to someone else's sin. If I would have put my foot next to a healthy foot, the infection would have been much more readily apparent. The trouble with sin is that it, like my infection, is more than skin deep. Even what we consider to be a minor sin is a much bigger deal in our hearts.
When we place our minor sins up against the perfection of Christ, it is abundantly clear that we have a raging infection in need of a cure. Our own sin-filled hearts cause us to ignore small things in our life until we are in need of life support. Thankfully, we can rejoice in knowing that Christ is our life support. His blood is our antibiotic. If you have come to saving faith in the Savior who had no sin, and placed your trust in Him, resting in His redemptive work alone for salvation, then you can praise Him for providing your "cure."
