If a belief is not proven 100% either way, then there is room for error in the conclusion. If there is error in the conclusion than another one can be looked for. So then, why not research the notion of a god or the existence of the inmaterial further? There are individuals out there who have set out to disprove the bible and the divinity and existence of Jesus and have ended up believers. According to the text, Living By The Book, this happened to a man by the name of Frank Morison. Frank and other authors like him provide beneficial talking points for the defense of a belief in God. Likewise, stories of near death experiences give credibility to the inmaterial aspect of humanity, the soul.
Topics such as these are what Christians of the 21st century need to be studying up on in addition to the bible. I am a believer that using the bible to prove your argument just does not cut it anymore. The spiritual war that Paul speaks of in Ephesians 6:12 has evolved to a more complicated war for the mind or the intellect as well as the soul. Secular scientists, whether they know it or not, have drawn their battle lines and it is time for Christians to prepare their minds and hearts for the intellectually spiritual battles that are before us. What I mean is simply this, both sides (secular and non) have faith that their belief is correct, so it is our responsibility as Christians to bring intellectual ammunition to the battle front.
As a final thought I wonder to myself, what it is that secular science is so afraid of regarding spirituality. It is my speculation that the secular world fears the loss of their facade called, 'absolute freedom in thought and action.' If secular science uses all of its resources to discover the validity of the spiritual world and proves its existence, they have to then deduce why it is there. The only explanation is to turn to what we as believers in the inmaterial turn to, religion and/or philosophy. Such a notion is rapidly discarded because it carries with it the presupposition that independence, autonomy and control over our own lives is gone; and in a world that embraces solely humanistic ideals such as self-actualization and becoming a fully functioning person, this is a terrifying thought.
