The world is changed by your example not by your opinion. (Paulo Coelho, Brazilian lyricist and novelist)
The belief in relativism makes self the ultimate judge of truth. What is true for you may not be true for me. So, personal opinion seems to be the ruling argument in any debate—whether in things like sports, movies, and TV or in more serious issues like religion or lifestyles. People will not respond so much to our ideas on those matters as to the integrity of our character.
Fools have no interest in understanding; they only want to air their own opinions (Proverbs 18:2).
Let everything you do reflect the integrity and seriousness of your teaching (Titus 2:7).
