In the gospels there are many calls to conversion and to lead a simple, sincere life in order to reach the goal of holiness. Perhaps the passage on which Claret comments in the text you have just read (Jn 14:6) has not been meditated on enough. Perhaps you have not realised that it is one of the deepest texts in all of Christian revelation.
It would be good to bear it constantly in mind and heart and meditate on it without ceasing, at least once or twice a day, during your working day or when resting. You could learn it by heart and make it the object of your prayer, paraphrasing, with the heart rather than the tongue, with the words that Blessed Teresa of Calcutta made prayer: Lord Jesus, sweet brother and friend: I know and firmly believe that you are for me the love I must love, the way I must go, the truth I must speak, the life I must live and the love who I must love.
The Christian is a person who seeks – or should seek – God continually, and the way of this search is Jesus of Nazareth, who became the way in this misdirected world. Let’s hope that you, as a believer, may choose the sure path and not other ways which can lead to perdition. The Christian is the chosen and predestined person who has hunger and thirst for truth and life. For you, and for all men and women of good will, the Lord is the truth and the life. You do not seek truth and life where lies and death reign.
Your closeness to the Son of God and Mary will be the guarantee of success, peace and glory. Approach the way of the Gospel, in it you will find the sure path, the truth which does not fail and true life: eternal life.
