The first time a bat invaded our home we dismissed it as a fluke. But after a second nighttime visit, I read up on the little critters and discovered they don’t need much of an opening to pay humans a visit. I had assumed they would need a gaping hole, but I discovered that if they find a gap as small as the side of a coin they’ll let themselves in.
So I loaded up my caulk gun and went on a mission. I went around the house and closed up every tiny opening I could find.
In Songs of Songs 2:15, Solomon mentions another troublesome mammal. He writes of the danger of “little foxes,” which can “ruin the vineyards.” Symbolically, he’s speaking of threats that can enter a relationship and ruin it. Now I don’t mean to offend bat-lovers or fox-lovers, but keeping bats out of the house and foxes out of the vineyard is a bit like dealing with sin in our lives (Ephesians 5:3). By the grace of God, the Holy Spirit works within us so that we don’t have to “live according to the flesh but according to the Spirit” (Romans 8:1). By the Spirit’s power we can resist the temptation to sin.
Praise God that, in Christ, we are now “light in the Lord” and can live in a way that “pleases” Him (Ephesians 5:8-10). The Spirit helps us catch those little foxes.
