The moral character and moral value of man's personality depends most of all on the direction and strength of the will. Of course, everyone understands that for a Christian it is necessary to have first, a strong and decisive will, and second, a will which is firmly directed toward the good of his neighbor, toward the side of good and not evil. How is one to develop a strong will? The answer is simple: above all through the exercise of the will. To do this, as with bodily exercise, it is necessary to begin slowly, little by little. However, having begun to exercise one's will in anything ( e.g., in a constant struggle with one's sinful habits or whims) this work on oneself must never cease. Moreover, a Christian who wishes to strengthen his will, his character, must from the very beginning avoid all dissipation, disorder and inconsistency of behavior. Otherwise, he will be a person without character, unreliable, a reed shaking in the wind, as we read in Holy Scripture.
We see the water of a river flowing uninterruptedly and passing away, and all that floats on its surface, rubbish or beams of trees, all pass by. Christian! So does our life. . . I was an infant, and that time has gone. I was an adolescent, and that too has passed. I was a young man, and that too is far behind me. The strong and mature man that I was is no more. My hair turns white, I succumb to age, but that too passes; I approach the end and will go the way of all flesh. I was born in order to die. I die that I may live. Remember me, O Lord, in Thy Kingdom!
It is a great good to give oneself up to the will of God. Then the Lord alone is in the soul. No other thought can enter in, and the soul feels God's love, even though the body be suffering.
No one can be saved without the renunciation of his will, even though he might struggle fervently, for our will and our manner are like a bronze wall between us and God.
