My Imaginary Friend

The other day as I was walking to my class at IUPUI, I passed the Democracy Plaza where students, faculty and staff gather to hash out differing thoughts and views on various topics of life. I saw this written on one of the plaza columns: "Adults who have invisible friends are stupid." At first I agreed with this, thinking "Yeah, that's pretty silly for adults to have invisible friends" and then it dawned on me that it was referring to Christians being stupid for believing in God. That's when I decided I didn't agree with it so much! But it did get me to thinking. That,  and this question I was asked during my BSF lecture on Monday night, "Why do I follow God?" Later that day I saw this video:

The thought I saw written on the column at IUPUI did not make wonder if I believed in a lie or cause me to think that I simply talk to a figment of my imagination when I pray to God. When asked why I follow God at BSF, I didn't feel as though the time I've spent learning about God, seeking after God, and living to please God throughout the years have been a waste of my time. I didn't need the argument presented in the video to assure me that God exists.  

So what did these questions get me to thinking about? If I think that God is more than just a fabricated invisible friend and that learning about God, seeking after God, and living to please God is worthwhile, am I living like I believe these things? Does my life show that I believe in a God who has the power, intelligence and artistry to create the universe? Does my life show that I believe in a God that is holy, loving and merciful enough to provide a way to justify sinners, give purpose to life and promise a future with Him? Or does my life seem to say that I believe in something as weak and meaningless as a childish imaginary friend?
