The issue of purpose couldn't be more important than it is today. As much of the Western World shifts away from religion and towards atheism (particularly materialism), they are left with a gaping hole in their lives. Without moral commands or the divine direction that once guided individuals and nations, many irreligious are left searching for that which can infuse their lives with purpose. Most end up landing on some system of self-purpose because it's easy, convenient, and unobtrusive. This system of self-purposing generally means that each individual must figure out or fashion their own purpose in life. Once a purpose is identified, then life can meaningfully be lived.

While self-purposing sounds fantastic (who wouldn't want to just follow their own desires?), there's one problem for materialists. Self-purposing is incoherent on their system. It can't be done. It's absolutely unintelligible. To discover why materialism cannot provide purpose - and especially self-purpose - I'll explore deeper the concept of purpose.  

​John Lennon, singer and song writer for the Beatles, was one of the most popular musicians of all time. But Lennon didn't just write music. He was a lyricist who incorporated his philosophy into his music. On the topic before us today, love, one of Lennon's more popular songs entitled "All You Need Is Love" declared just that. All we need is love. Lennon wrote another very popular song entitled "Imagine," which was a vision of how we could build a world saturated with the love Lennon thought we needed. Lennon says, "Imagine there's no heaven. It's easy if you try. No Hell Below us. Above us, only sky... You may say that I'm a dreamer, but I'm not the only one. I hope some day you'll join us. And the world will live as one." In Lennon's mind, religion was an impediment to love, not a conduit. If we could just get rid of religion - if we could just get rid of the division religion causes, then the world could finally be free to love. 
​
Unfortunately, Lennon was a far better musician than he was a philosopher. But despite his poor philosophy, his beliefs have been peddled to hundreds of millions of listeners throughout the decades, and his beliefs have unfortunately gained popularity. Like Lennon, many today believe that love would be in a much better condition if we could just rid it of the burden of religion. However, I am here to tell you that without religion - specifically without a religion like Christianity which has a relational God at its center - love is dead.​

Some recognize that objective morality exists, but don’t recognize its grounding in God. And some people deny that God exists altogether. This particular topic, the absurdity of life without God, starts from the very beginning. It is largely geared towards individuals who view meaning, value, and morality as being wholly independent of a divine being. Therefore, it is a particularly powerful argument to use with atheists. However, it is also a great discussion to have with Christians who are doubting their faith, or considering the strengths of atheism. This topic provides us with the motivation to seek out whether or not God exists, and spurs us on to find the deeper answers of how those aspects play out. While it doesn't lay out evidence for the existence of God (Craig will do that in the next chapter), it does paint a vivid picture of what a life lived consistently and without delusion should look like under atheism.
