The word πείρα (experience) lies behind the concepts of πειρασμός (temptation), πείραμα (experiment), πειράγματα (teasing) etc. and we all understand how important the concept of experience is.
Indeed, it is obvious that the experience of others does not have the same intensity and value as personal experience. What you are experiencing cannot be transferred. Images and words can be transferred, but not the experience that always remains absolutely personal and irreplaceable.
For this reason everyone has his or her own personal experiences and they depend mostly on them. My individual experience leaves its traces in my life, I learn from it, and experience is the key element in every experiment. We try something, and by positive or negative experience, we continue or interrupt the experiment.
There is no progression without experiment and this indicates the value of the concept of trying. In the life of faith no one wants experiments. We all want security and certainty. Without personal experience, however, without personal experiments and personal evaluation of the results, there is no certainty about the course I follow.
Inertia and inaction are the opposite of experience and experiment. The first ones kill, the others promote and enrich.
