Religious people don't tend to rely on Ti explanations for their belief systems.
The whole idea of faith is that it's not inherently reasonable; if it was, everybody would be able to believe it in effortlessly.
Actually everyone believes in some form of faith, as it is a fundamental component of the 4 schools of thought : Ethics, Physics, Epoptics, and Rational, otherwise known as moral, natural (perception), faith, and reasoning. All of these modes of thought are intertwined within the human psyche, though individuals differ in their preference of use.
I have a more rational explanation for my faith; but keep in mind that no rational conclusion cannot be drawn without first having faith that your rational premises are founded, and even further that your initial perceptions do not betray you:
Firstly, I will say that I believe that there is a Supernatural Causation, and second that Jesus is the Son of God. The latter requires more faith for me than the former.
We occupy a natural structure known as the universe. Within the universe, there are natural laws which man has established, while anything that transcends these laws is considered supernatural.
1. For every cause, there is an effect.
2. Matter cannot be created or destroyed.
The universe operates on the conjoined frameworks of time and space. Before the universe existed, there was no time or space; though the Big Bang theory suggests a singularity of mass prior to the expansion of existence. However, if there was a singularity, there must have been a cause for the singularity. Given premise #2, we can deduce that it was not created, but we can hypothesize that it contracted from a prior universal state. This would indicate a sort of cosmic egg of universal timelessness. However, it would also indicate that the universe would not have a cause of creation - It would be eternally causing and effecting itself. This would defy rule #2 because matter cannot be created within the constraint of natural law . As long as we abide by natural law to describe the onset of the universe, we cannot accurately assess the act itself. Therefore, either there is a Supernatural Causation, or natural law is inaccurate.
My faith in Jesus comes from the fact that He claimed to be the Son of God with the implementation of historical research. Plus faith. I'm still treading a path.
