Recognizing influence

It is somewhat difficult and obviously uncomfortable, to honestly identify those things that are influencing and directing our thinking.  Especially in the area of appearance, the culture in which we live will, undoubtedly, seriously influence our thinking and actions.  What we consider beautiful, cool, acceptable and favorable will be influenced by our culture. 
The extremely difficult thing about this is that because we find these things "good", we will feel inclined to justify these things, even when they may be contrary to historic Christianity.  It is difficult to be objective when the subjective is so enticing.  Work to the point of blood and talk to your priest.
