By our negligence and bad habits most of us fall into insensibility and blindness and do not even know that God exists, or what we are, what we have become as sons of God sons of light, children and members of Christ. Were we baptized as adults? We saw only the water and not the Spirit. Even if we have been reborn in the Spirit our faith is dead and inactive…We have become flesh and we live according to the flesh… There are two ways of finding the activity (energy) of the Spirit that we received sacramentally in Holy Baptism:
a) By the observance of the commandments and at the price of long efforts we may achieve in a general way a revelation of this gift…
b) It is revealed in a life of obedience (to a spiritual father), by the methodic and continual calling upon the Lord Jesus, that is, by the remembrance of God.
The first way is longer, the second is very short, provided that the soul has learned to dig the ground courageously and perseveringly in search of the hidden gold.
