For a long time I wondered why God has His preferences, and why souls did not all receive the same measure of grace. I was astonished that great sinners like St Paul, St Augustine and St Mary Magdalen should be granted such extraordinary favours, and almost forced to accept them. When reading the Lives of the Saints I could not understand why our Lord treated some as privileged souls even in their cradles, removing any obstacles that might keep the from Him, and preserving unspotted their baptismal innocence, whilst on the other hand innumerable savages died without ever hearing the name of God.
Jesus Himself taught me this mystery. He laid open before me the book of Nature, and I understood that all the flowers He has created are beautiful; that the loveliness of the rose and the purity of the lily in no way lessen the sweet scent of the hidden violet of the appealing simplicity of the daisy. I understood that if all the little flowers wanted to be roses, Nature would lose her garb of Spring, and the fields would no longer be starred with little blossoms. It is the same in the domain of souls, the living garden of the Lord. (St Therese 'Story of the Sols')
