Isaiah 49: 7 - I will give you as a light to the nations, that my salvation may reach to the end of the earth.”
In Isaiah, God seeks to call his people back to him by sending his servant as a light to the nations so that his salvation may reach to the end of the earth. To achieve this end God eventually sent Jesus Christ, his only son, to bring salvation and be the light to us all. The light of Jesus Christ continues to live in all of us. It is a light that was given to us as God formed us in the womb. It is a light that was reaffirmed at our baptisms when our baptismal candle was lit from the Paschal candle and presented to each newly baptized person with the words receive the light of Christ. It is a light that we are called to let shine brightly whatever we may be doing.
