O Light Eternal, who come to this earth, enlighten my mind and strengthen my will that I may not give up in times of great affliction. May Your light dissipate all the shadows of doubt. May Your omnipotence act through me. I trust in You, O uncreated Light! You, O Infant Jesus, are a model for me in accomplishing Your Father’s will, You, who said, „Behold, I come to do Your will.” Grant that I also may do God’s will faithfully in all things. O Divine Infant, grant me this grace (D. 830).
These words of prayer filled St. Faustina’s heart on Christmas Day. They were the result of her great preparation to this holiday in which Mary accompanied her: My daughter, strive after silence and humility, so that Jesus, who dwells in your heart continuously, may be able to rest. Adore Him in your heart; do not go out from your inmost being. My daughter, I shall obtain for you the grace of an interior life which will be such that, without ever leaving that interior life, you will be able to carry out all your external duties with even greater care. Dwell with Him continuously in your own heart. He will be your strength. Communicate with creatures only in so far as is necessary and is required by your duties. You are a dwelling place pleasing to the living God; in you He dwells continuously with love and delight. And the living presence of God, which you experience in a more vivid and distinct way, will confirm you, my daughter, in the things I have told you. Try to act in this way until Christmas Day, and then He Himself will make known to you in what way you will be communing and uniting yourself with Him (D. 785).
And it happened as Mary promised. Jesus Himself told Sister Faustina that fulfilling her desires for unity with Him consists in faithful fulfilment of His will. Let us wish one another this grace that we may have the same desires as Jesus has towards us.
