When Jesus was asked about healing via belief...He said "let it be according to your faith". I think there are studies and documentation of stats which reflect the healing power of faith.

Re the Bible (Basic Concepts, notwithstanding all the questionable translations, metaphors, meanings, et al), I believe that the basic Idea that the 'physical' Universe is indeed a derivative of a Spiritual, Self-Aware 'Entity'. I.e., God; with all the baggage therein.

As Science becomes more knowledgeable, the basic essence of this 'perceived' Universe becomes more abstract, exponentially complex and incomprehensible by the day.

I also believe that the Biblical, Christian narrative of Jesus Christ as the Original Mold, Liaison, Guide and 'Savior' for our flawed (via our limitation) Humanity, is both logical, philosophically sound, and common sensical for those who have experienced Love to a great degree. Especially those who are loving and responsible Parents.

I also believe that ultimately, one becomes the product of one's EDUCATED CHOICE. God gave us the gift of our 'Self', it is up to us - as it should be - what our ultimate value and 'Self' will be. IMO, in life, we are perusing the 'buffet' of choice, in order to attain said education, in order to make that educated choice. In this scenario, 'perception becomes reality', and that is how different individuals can exist in totally different perceptive realities. Perception, being based on belief.

To each their own. Though, as those who choose the opposite of Love (extreme Narcissism/Self Worship) they will not rest easy if able to observe those who have chosen Love and enjoy the rewards therein. Enter, Satan, and the power of Evil. As long as there are 'Individuals', there will be 'Evil'. Envy rules. Cain v Abel.

And, I too have experience 'miraculous' events. All questionable by skeptics of course. Albeit, the Bible says that miracles are not for unbelievers, but believers.

God speed.
