Bad influences work fast.
I left a barber in town because he didn’t cut my hair good. Plus he didn’t razor cut above my ears or put hot shaving cream on my neck; you know, the little things that make a hair cut better. So, I found a second barber who did everything right. But then he told me he was closing his shop to join another barber, and wouldn’t you know it, he moved in with the bad barber I’d just left! Unlucky me!
After the move, when I went back (on the bad barber’s day off) he cut my hair beautifully just like always. But three weeks later when I returned (still on the bad barber’s day off) he cut my hair as bad as the other barber did. He hurried through the cut like he was nervous, left it way too long, and did not razor cut above my ears or shave my neck. What in the world happened!
On the way home it hit me, the good barber was already under the influence of the bad barber. If he doesn’t get out of that shop soon, he’ll be ruined. Of course, the opportunity for the good barber to influence the bad barber was there too; but it doesn’t often work out that way in this old sinful world. That’s why Paul warned us in 1 Cor 15:33, Do not be deceived: "Evil company corrupts good habits." NKJV Beloved, beware of bad influences! They work really fast.
