The doorbell rang and my wife went to the door. It was John our neighbor who reported, “I saw some people walking down our street. They jumped and squirmed. I didn't know what was going on, then I realized it was a snake! Mrs. Martin, I am sorry to tell you this, but that big black snake was last seen entering your yard.”

Now what do you suppose we did? Did we ignore his warning? No. My wife walked around our house with a stick. The next day when I mowed the lawn, I kept my eyes peeled. We were vigilant.

God told Cain, “Sin lies at the door. And its desire is for you, but you should rule over it” (Ge 4:7).

Do we take sin as seriously as we do snakes? Shouldn’t we be alert and watch where we step?!
