In this sermon, Pastor Nate accepts a challenge to demonstrate that believing in God is actually the most reasonable and rational explanation of reality. There are four reasons to consider. First is the big God behind the "Big Bang." Second is a fine-tuned universe that sustains life. Third is the existence of transcendent beauty, desire and meaning. Fourth is that belief in God is an anchor for morality. The sermon also addresses the scriptural explanation for unbelief while affirming the ultimate evidence of God's existence--Jesus Christ.
