I've been of the belief that miracles are unexplained science or what author Arthur C. Clarke once said, "Magic's just science that we don't understand yet."
From my research and study of the Bible, I believe that the personality of the Christian God YHWH and by extension Jesus Christ, was to act within the rules and boundaries of their own created system. I don't believe God was the type who snapped His fingers and 'BAM' there's a miracle. In fact, in such a perfectly balanced scientific system, snapping your fingers to create would be almost irresponsible. So, Imagine creating the earth, such a diverse and complicated equation of science and physics, and then not using it.
Imagine all the scientific theories out there that we do not comprehend. Black matter, worm holes, 4th dimension, 5th dimension, even time itself! We corroborate that there's a high likelihood that these ideas exist but can't figure out how to harness their energies. If you believe that Jesus was and is God, which I do, or even if you allow yourself to speculate on it. If Jesus is God and he wrote all the strings of the equation that make this earth and universe work, then he could easily access these energies that are currently beyond our imagination or belief and use them to perform miracles. All this, within the confines of creation.
For example, at one point, fire was probably thought to be magic. Until we understood the science. Imagine a flying plane or an iPhone 500 years ago.
I enjoy theorizing this concept throughout the bible. Would love to talk more about this if anyone is interested.
