There is a God. Though he is not physically with us or speaks audibly to us, there are undeniable, tangible markers in the world that testify to his presence.
The first is that we are here. There is no dispute that the probability of the simplest life forms appearing on a planet, let alone the existence of complex humans, is effectively zero. Yet, despite the logic of science and mathematical probability, here we are. The likelihood that you exist is 100% (because you are reading this), but the probability of you existing is zero. Is it reasonable to believe that the incredibly slim odds were beaten by chance alone?
Also, consider the astounding diversity of living things here on Earth. There are so many different species that no one can count them. The latest educated, authoritative guess is over 8.5 million, give or take a million. Present in these millions of species is a vast spectrum of configuration that seems to speak of influence well beyond the pressure of the environment or adaptation needed to survive over time. For example, the blue whale weighs 400,000 pounds, and the tiny bumblebee bat only 7/100 of an ounce. One lives underwater, and the other flies through the air using the echo of his screams to find and catch bugs. It seems improbable that evolution could account for the dramatic diversity of the animals on the Earth. Instead, I would suggest that the massive inventory of diverse and distinct flora and fauna is credible evidence of God’s work.
Then there is morality, the knowledge of good and evil, and the principles concerning the distinction between right and wrong. In nature, it is correct and acceptable for the strong to prey on the weak and for the cunning to deceive the naive. There is no wrong in nature; there is only the way things are. But in human society, even though the definition and perception of morality may change somewhat over time, we recognize that some actions and behaviors are good, righteous, and noble, while others are immoral, wrong, and unacceptable.
I doubt there would be disagreement that genocide is immoral or that sacrifice for others would be deemed righteous. It is easy to recognize the evil in our world, such as the depraved wretch that murdered his mother and then massacred 20 precious children at Sandy Hook elementary. It is also just as apparent that one who would volunteer his life to save another, or to save everyone, is the pinnacle of virtue. If there is only nature, with no distinction of morality, then what accounts for our fundamental recognition of wrong or right and good or evil? Did we become aware of the difference by upbringing, intellect, and experience? Or do we live in a world created by a God who intends for us to live above the instinct of nature?
The evidence is compelling that there is an architect and creator, but drawing that conclusion, or rejecting it, are both acts of faith. Some will believe that the existence of God is obvious and that to conclude otherwise defies reason. Others will put their trust in the infinitesimal odds that this all has occurred by chance.
