"The nature of faith
Our soul possesses the amazing ability to sense God. Although this awareness of the Divine presence is weak and hazy in a person just beginning to grow spiritually, it gets stronger and becomes more and more conscious with a virtuous way of life. This, in turn, strengthens one's faith in Him, so that the inner feeling of God grows to a strong religious conviction. In such a state, the omnipresence of God, His infinite love and fatherly care are continuously felt and become a source of inner peace and strength.
True faith cannot be satisfied with a cold recognition of God's existence but strives to be in close communion with Him. The believing soul naturally reaches to God, as a sunflower turns toward the sun. In turn, an active relationship with God further strengthens the person's faith, so that his faith becomes a spiritual guide, based on personal experience. In some particularly gifted people faith grows into an all-illumining and constantly inspiring idea, that leads them from this world of vanity into the transcendent world of eternal life. Among such people were the Virgin Mary, Saint John the Baptist, the Apostles John and Paul, and countless saints like Sergius of Radoneszh, Seraphim of Sarov, John of Kronstadt, Herman of Alaska and Blessed Xenia of Petersburg, to name just a few.
The significance of faith in a person's development lies in that it gives proper direction to all his aptitudes and powers. Specifically, it gives clarity and the correct outlook to his intellect, direction and purpose to his will, it ennobles and refines his senses. Faith brings harmony to a person's inner world. It frees one from base earthly interests and leads him into a realm of higher and holier experiences. "
