The second reading for the 5th Sunday of Easter(Revelation 21: 1-5)states:
Then I, John, saw a new heaven and a new earth... I heard a loud voice from the throne saying, 'Behold, God's dwelling is with the human race. He will dwell with them and they will be his people and God himself will always be with them as their God. He will wipe away every tear from their eyes, and there shall be no more death or mourning, wailing, or pain, for the old order has passed away.
What is this new heaven and new earth? It must be because God makes all things new and he will dwell with us. It is consoling to read that he will wipe away every tear and that there will be no more death and pain. Our world is so full of both and yet we know that God will come and there will be no more mourning, only joy because he is with us.
The Communion Antiphon is one of my favorite passages from John 15:5
I am the vine and you are the branches, says the Lord; he who lives in me, and I in him, will bear much fruit, alleulia.
