I wrote Physics of Faith to challenge the idea that faith is passive, abstract, or proven through suffering alone. For much of my life, I believed hardship was not only inevitable but required, that endurance was evidence of righteousness. My valley trained me to tolerate pain. My mountains forced me to question whether tolerance was ever the goal.

Over time, I began to observe faith the way one studies motion: through cause and effect, inputs and outputs, resistance and acceleration. Faith, I realized, is not static belief, it is an active system. It operates through cognition, behavior, environment, and time. When belief changes thought patterns, thought patterns alter decisions.
