"Faith is not belief without proof, but trust without reservation"

This quote by D. Elton Trueblood implies that faith does not require concrete proof or logical evidence. It is not merely a blind approval of a set of beliefs or doctrines. Instead, Trueblood recommends that true faith involves trust in something or somebody without any appointments or doubts. Faith is not simply a mental exercise, but a psychological dedication to an idea or a person. It requires a deep level of confidence and conviction in a belief system, and a desire to act based on that belief. In essence, faith is a relationship of trust that transcends empirical evidence or logical arguments.
