Hi Yall!
Some of my thoughts- Is it reasonable (literally) to believe in God? Well, is it reasonable to believe that the Empire State building had an architect? Yes, I think so, and why? What do we have as proof of the existence of that architect? Very simply, the building itself! The building itself is the evidence of the existence of the architect.
Now then look at the universe, or even just the human body. There is more design in the human body than the most intricate, complex man-made computer enhanced machinery in existence. We as humans cannot even come close to performing an eye transplant let alone create one. The Cell is an amazing example of a perfectly working machine, the examples could go on and on. So, as a matter of logic, it is highly unreasonable and illogical to believe that although such design exists in our universe, there is no designer behind it. One of the reasons why many of us resist the reasonableness of God's existence, is that we resist the ramifications it may have to us personally. I may prefer to be the master of my own domain, and I don't need a God to infringe his laws on me....
But if God exists, then the question is what can we know of him? How has he revealed himself? And for a last thought on that, I'll quote someone else...."For his invisible attributes can be clearly seen though what has been made...."
