I heard a seminary professor tell a story about eating dinner with a famous evangelist just before a large evangelistic meeting. The two were eating dinner when their waitress spilled water on the evangelist. The evangelist became furious at the waitress because of the accident. He began to belittle her to the point of humiliating her.
After the waitress left the table, the professor said to the evangelist, "I dare you to share the gospel with the waitress." Of course, he knew that he could not say anything to the waitress after the way he had spoken to her. He was too ashamed, and rightfully so.
Trying to share the gospel with someone that you have treated like dirt borders on blasphemy. What would that person think of your Lord? A life of integrity, kindness, and humility makes the message attractive. Anything else is counterproductive.
(To give credit where credit is due, someone under the name "tjclaud" posted this on a message board I read occasionally.)
This is a great reminder to us in our everyday encounters. That includes your spouse, children, waiters and waitresses (whether they are good looking or not...), telemarketers, fast food employees, and the guy from the cable company.
That doesn't mean there will not be conflict. It just means you need to conduct yourself in a way that would not undermine the ultimate message you want to share and live.
We take captive every thought to make it obedient to Christ.
2 Cor. 10:5
Lord, help us all.
