This last Sunday we looked at the way that we tend to reject God as king so we can work at building our own little kingdoms.  Paul Tripp, in his book "A Quest for More," does a great job articulating this principle.  Here are a couple of quotes from it:

In a fallen world there is a powerful pressure to constrict your life to the shape and size of your life. There is a compelling tendency to forget who you are and what you were made for. There is a tendency to be short-sighted, myopic, and easily distracted. There is a tendency to settle for less when you have been created for more. There is something expansive, glorious, and eternal that is meant to give direction to everything you do. And when you lose sight of it, you have effectively denied your own humanity.

Sin Causes fundamental changes in the ‘molecules’ of my heart. No longer is my heart driven by a deep-seated love for God. No longer is my heart motivated by a genuine care for others. No longer do I carry around a sense of responsibility for the surrounding created world. No longer is every decision I make shaped by a clear sense of what is morally right and morally wrong. No longer is everything I do shaped by joyful and thankful worship. The DNA of sin is selfishness, and it shrinks the size of my universe to the size of one. Sin creates the ultimate shrink dynamic. It causes all of us in some way to shrink the size of our lives to the size of our lives. Sin shrinks my motivation, zeal, desire, care, and concern to the contours of my life. In the shrunken kingdom of self, there is no functional room for God or others. It is humbling, but spiritually essential, to admit that sin has shrink-wrapped us all.
