Titus 2:7-8

In the past few verses of this chapter there have been specific instructions for different groups of believers. Now, these instructions are for everyone--don't do anything stupid!

There has been a situation in the NBA over the past few weeks which has demonstrated this concept particularly well. The owners of NBA teams have a mandate from the league that they are not supposed to do anything which is detrimental to the image of the league. One owner recently stated some very racist views...which are detrimental to the league. The other owners voted to force him to sell his team. They are so upset and disappointed that they want him to be gone.
Now, as a believer you will never be "voted off the island," but the concept is there--don't do anything which will allow opponents of Christianity to speak against us. Be thoughtful, mature and careful.  
Titus 2:7-8  Show yourself in all respects to be a model of good works, and in your teaching show integrity, dignity,  8 and sound speech that cannot be condemned, so that an opponent may be put to shame, having nothing evil to say about us.
