1. I glorify and praise God, my sisters, that you have received Communion once again today. May it be for your life, health, and salvation for life in Christ, for health of soul and body, and for eternal salvation in the kingdom of heaven, in the Mother of God, the kind protectress of our holy convent.
2. Now you feel light, serene, and joyful. You also feel fearless and powerful, because the Almighty Christ has taken up His abode in you and you have taken up yours in Christ. Now it is easier for you to resist every evil, visible and invisible. For the mighty Lord will fight from within you and for you against every evil power. And before Him every evil power is like fog before a mighty wind. Therefore, fear no one.
3. I mean, fear no one and nothing except sin. For every sin weakens your bond with the powerful Christ. If the sin is small, it still weakens your bond with Him; if, however, the sin is great, it can completely sever your bond with Him leaving you alone, without His help against all the evils in the world and against all your enemies, visible and invisible.
God forbid! Remember that He said, "Without Me you can do nothing." Truly, Lord, absolutely nothing.
4. Moreover, having taken Communion you now feel more alive. You have become one with Him, and He is full and overflowing with life like a fountain of living water, as He once told the blessed Samaritan woman, Photina, at the well of her forefather Jacob (cf.John 4:542)...the Lord is our reliable and inexhaustible fountain of living water, a stream of eternal life. Therefore, He said that He had come down into the world to give life to His followers, saying: "I came that they may have life, and have it abundantly" (John 10:10). Not just life, then, but the fullness and abundance of life the brimming chalice of living water that "runneth over." You are feeling this abundance of life, especially now after Holy Communion.
5. Life, life, and only life. Joy, joy, and only joy. A full life is a full joy. An empty life is an empty joy. The holy kind David never saw Christ, nor did he ever partake of Christ through Holy Communion, but only felt the prophetic premonition of His coming into the world. Yet even this mere premonition filled his heart with such joy that with all his strength he danced and leapt for joy (2 Samuel 6:1416). And how much more ought we, dear sisters! How much more ought we to dance for joy, since we were deemed worthy to be born not in the time of the Old Testament, but of the New Testament and not only to hear about the Saviour, the Son of God, but even to eat His body and drink His blood, and to receive Him into our heart and to give our heart to Him with love, love, and more love; with joy, joy, and more joy.
6. I do not know how to explain to you the sublime mystery of Holy Communion, my sisters. It is beyond my power...Whenever I myself have thought about this, out of nowhere the question enters my mind: Can you really explain what air is, what bread is or what water is, and yet you cannot live without air, bread or water for even a little while? And this brings me peace...
