Science will never prove there is not a God because it is the study of natural things, and God is supernatural. Religion shouldn’t be afraid of science because God set up the world with natural order and precision. Using one to argue against the other is a little like using history to argue math. The one fact we can all agree on is that we are here. No matter how we got here, there is an earth, a heavens and intelligent life.
The question shouldn’t be simply “Is there a God?” it should be “If there is a God, what is His nature?” Because if God is not a loving God, does it really matter if he made the universe? If a god simply wound up the clock of time and set the universe in motion, not caring for its creation, what difference does it make today that he exists. If the creator isn’t loving, and there is no eternal place for the soul, then for all intents and purposes, it doesn’t matter how we got here, or really, what we do while we are here.
If God is loving, if the God of the Bible is true, then it does matter. A loving God who cares about His creation and has an eternal plan for it is the opposite of not only atheistic views but theistic ones as well.
What would be the evidence of a loving God? There are miracles; events that happen outside of the natural order of things. Miracles do occur; I have been witness to more than one miraculous healing. You could also point to chance happenings that would suggest that there is someone looking over us and bringing into our lives the people we need, just when we need them. Of course, you could brush them away as just coincidences, but I have had them happen in my life more often than I can recall.
What better evidence would there be to the nature of God than to have Him tell us? For that, God gave us the Bible; throughout the scriptures, God reveals His love for His creation, especially humans. The testimony is written down and has been kept safe throughout the ages. Every generation and culture can relate to it; its message is timeless.
We are again presented with a choice; we can look at the evidence and decide that there is a loving God who cares for us and longs to have a relationship with us, or we can reject it as fairy tale, folklore and coincidence. It takes faith to believe either way. To believe in a loving God is to take the scriptures as true and see the miracles that are around us as acts of love. For the atheist or theist, you must believe that the scriptures are not absolute truth and believe that miracles are nothing more than random luck. The key question is “what do you do with Jesus?”
