Libermann advises Eugene, "Do not run farther than grace propels you." He is not to rely on his own strength but the strength of God at work in him. "... When our trust rests solely in our adorable Master, what difficulty need we fear? We will stop only when a wall blocks us. Then we wait with patience and confidence until there is a breach and resume our march as if nothing had happened."
Libermann provides an incisive commentary into the prayer O Jesu, Vivens in Maria (O Jesus, living in Mary). Like Mary, Eugene is to give himself "to our divine and most adorable Lord to die and live in Him." In this correspondence (letter 10) Libermann outlines three stages for Eugene to follow in his desire to open himself up to the life of God.
First, to free himself from a preoccupation with external activity, as "the work of becoming holy must take place in the interior of the self." Second, to cooperate with God's grace at work in him. Referring to St. Paul and the Gospels Libermann writes, "You will not find in them any praise of a good character as being the source of great holiness. On the contrary you will see on every page how grace does everything." Third, Eugene must overcome the fault of judging others unfavorably. "Examine things carefully and you will see that in matters of perfection the judgers are usually inferior to the judged."
