The reader has in his hands a precious treasure through which he can get to know Saint Faustina in the daily life of her life.
In times of great anxiety, loneliness, lack of meaning, security and love, Saint Faustina teaches us – with her life – the secret of her holiness, teaches us the spiritual path that Jesus himself led her on, teaches us to contemplate God in everyday life, teaches us to discover the Lord in our own soul and to live in communion with Him throughout our lives, and, as a consequence of this communion, to be merciful as the Father in Heaven is merciful.
