Only let your conversation be worthy of the gospel of Christ; Philippians 1:27
You may or may not be aware that the PG-13 ratings, on movies, continue to slip downward with more and more curse words allowed. You may have seen Donald Trump use the F-word in his speeches and the crowd goes wild. You may have heard that the Brooklyn Public Library allows porn to be viewed on the computers, allowing those who pass by the ability to view it. You may have seen the increase of bleeps on regular cable TV, not including specialty channels like Showtime or HBO. This may or may not bother you, but if you love Jesus and desire peace and salvation for the lost it will.
Decay is a process over time that removes the integrity of its object. Christians can decay when we allow the decay to contact us. We allow the decay to contact us when our conversation reflects the world around us and not the gospel of Jesus Christ. If you call yourself a Christian and use curse words how do you justify the verse above? If you call yourself a Christian and tear others down and do not edify your family, friends, neighbor and enemies how do you justify the verse above? If this verse does not affect you at all why do you call yourself a Christian?
The world often accuses Christians of being hypocrites, but are those who are lost (Bible is not their guide), hypocrites calling themselves Christians when they are not?
