Is it just me, or does this seem stupid? If you can't see this huge windmill, then why put up a small sign? Just doesn't seem to make sense to me at all!!! But, in another way it does, because people see exactly what they want to see and nothing more. Consider Paul's letter to Titus for a moment...
WEB: Titus Chapter 1
 To the pure, all things are pure; but to those who are defiled and unbelieving, nothing is pure; but both their mind and their conscience are defiled.
One more time... we see what we want and nothing more. Somehow, the species called Homo Sapiens finds a way to justify its thinking. Don't think so, then, I wonder why someone coined the phrase "the end justifies the means"? We can look at life anyway we want; we have a choice. Remember; is the glass half full or is it half empty? We can choose to pursue purity or impurity and once we do, somehow we will see goodness or evil in the world around us. Seeking God (the author of purity) makes us see those things wrong with us and want to become better. If we make the choice to do whatever WE WANT, then we become the focal point and we can do NO WRONG, whatever we decide to do. Humm, somehow the end justifies the means comes to mind (again). That's it, precisely. Home plate, X marks the spot. Anything more is just encouragement to make the right choice, but then again...I too have my mind made up. Can you guess where my "X" is?
