Then there may be times when in the ordinary course of our work we are where some very defiling talk is going on. There may even be an attempt made to entangle us in it. In such cases we should reprove their works of darkness. We may get into circumstances where our silence would be a mistake and would lend our sanction to what is said or done.
A Christian man traveling on a train through the northwest walked into the wash room. As he entered he heard one man telling another a vile story. This child of God did not wish to even hear the story, so he walked straight to a wash bowl where his back was to the two men. There, without turning to see which one was the speaker, he said quite audibly: “The Word of God says, 'Fools make a mock at sin.'" Prov. 14:99Fools make a mock at sin: but among the righteous there is favor. (Proverbs 14:9).
On hearing the solemn word of reproof, the conversation stopped instantly with apologies. We do need wisdom from above to know just when we should reprove the works of darkness.
