The story is told of a principal of a small middle school who had a problem with a few of the older girls starting to use lipstick. When applying it in the bathroom they would then press their lips to the mirror and leave lip prints.

Before it got out of hand he thought of a way to stop it. He gathered all the girls together that wore lipstick and told them he wanted to meet with them in the ladies' room at 2 pm. They gathered at 2 pm and found the principal and the school custodian waiting for them.

The principal explained that it was becoming a problem for the custodian to clean the mirror every night. He said he felt the ladies did not fully understand just how much of a problem it was and he wanted them to witness just how hard it was to clean.

The custodian then demonstrated. He took a long brush on a handle out of a box. He then dipped the brush in the nearest toilet, moved to the mirror and proceeded to remove the lipstick.

That was the last day the girls pressed their lips on the mirror!!!

I know......that's disgusting!!!! But sometimes it takes something disgusting for us to recognize the seriousness of what we have done.  Like my sins, for example.  I'm often tempted to take them lightly ("they're not really so bad"). Sometimes I need to be shocked by the realization of what happened on the cross because of my sin.  The spit running down Jesus' face, the blood gushing out, the excruciating agony of spikes being driven into his flesh.  It's not a pretty sight.  In fact, it's disgusting! But it is in that disgusting sight that I find
the strength to turn from the sin I may be contemplating.

"Then they struck him on the head with a reed and spat on him; and bowing the knee they worshiped him. And when they had mocked him, they took the purple off him, put his own clothes on him, and led him out to crucify him."
(Mark 15:19-20)
