Is it really possible to deny God only because everyday experience does not give Him to us? But we know that “everyday experience” is in no way absolute, that it encompasses only some superficial sides of events and phenomena, that plain common sense is limited, and that there are many irrefutable facts which do not fit into what would seem to be unshakable, self-evident truth. Everyday experience gives us almost none of the things modern scientists talk about, but we believe their experience; we believe them without even knowing them or having the remotest possibility of testing the larger part of their assumptions and conclusion. On what grounds do we disbelieve the innumerably greater quantity of religious experiences, the testimony of people who are pure as crystal?
The experience of these experts in the “science of sciences” does not speak of unsubstantiated faith, nor of opinion, nor of an accepted hypothesis, nor even simple tradition, but of the fact of their knowledge of God.
The main experience of religion – a meeting with God – possesses (at least in its highest points) such a victorious power and fiery conviction, that it leaves any other obviousness far behind. It can be forgotten or lost, but not denied…. If people of faith began to tell about themselves, about what they have seen and learned with final certainty, then a whole mountain would form under which the mound of sceptical rationalism would be buried and hidden from sight.
Knowledge of God is an exact science, and not a chaos of mystical ecstasies and unhealthy exultations caused by inflamed nerves. Knowledge of God has its own systems, conditions, and criteria. How can we attain the knowledge of God? It begins with a selfless search for the truth, for the meaning of life and moral purity, and by forcing oneself towards goodness. Without such a beginning, the “experiment” of knowing God cannot be successful. These conditions are expressed in the Gospels briefly and clearly: “Blessed are the pure in heart, for they shall see God”.(Mt 5:8).
