First appearances led me to think this window sill was whole, but now, upon closer inspection, that's obviously not the case. Those little creatures have chewed out most of the inside of this sill. In fact, I'm not sure what's holding the paint on. You look at your neighborhood, see manicured lawns with neighbors going off to work each morning, and you think everything is alright. Or, you look at brothers and sisters in the Lord on Sunday, thinking all is well, only to be shocked by some sinful breakdown over time.
Sin has a way of doing that.
It creeps in, like termites, tunneling its way into your life, gnawing at the defenses we have erected, gradually wearing them down, so that one's thoughts, desires then actions, become increasingly eaten by unrighteousness. Before you know it, you're walking around, looking fine on the outside, but your soul is eaten with sin, having become duplicitous and corrupt. The only answer is radical surgery. Just as this window sill will have to be torn out and a new one installed, so we too may have to have the corruption cut out of us, replaced with that which is whole and new. Jesus does that kind of surgery.
