In the readings for today's Mass, Jesus warns us not to hide our light under a bushel basket. He is not simply saying that we shouldn't be afraid to show off, or to honk our own horn but he is simply saying that when God asks us to allow his light to shine through us that we not hinder him.
In following Jesus we will be led up both the mountain of Tabor, of transfiguration, glory and exaltation, and we will also be led to the mountain of Calvary, of suffering, sorrow and humiliation. He trod this path first and asks us also to follow him. To him these are just different expressions of following Abba and his direction.
Blessed Pope John Paul had said in a homily that the light from Tabor and Calvary is the same. St Faustina, the polish nun who had revealed the Divine Mercy said that the light from the Risen Christ in the image of Diving Mercy was the same that came from the light of his face while he hung upon the Cross - the light of diving Grace and Mercy.
May Our Lady help us to be faithful in following Christ through all the hills and valleys, highs and lows, exaltations and humiliations for the glory of God the Father.
