Advent is a time of waiting

Advent is a time of waiting; we desire to celebrate Christmas and our desire increases with our singing of 
"Slowly rolled the ages..." I guess it is a good time to learn to be patient and wait in silence for the coming of the Lord.
Today I will be waiting with one of my sisters who I will take to the hospital for surgery; she has been waiting for the operation and I will be there to wait with her.
Here is another excerpt from the Holy Father's Apostolic Exhortation;

4.
The books of the Old Testament predicted that the joy of salvation would abound in messianic times. The prophet Isaiah exultantly salutes the awaited Messiah: “You have multiplied the nation, you have increased its joy” (9:3). He exhorts those who dwell on Zion to go forth to meet him with song: “Shout aloud and sing for joy!” (12:6). The prophet tells those who have already seen him from afar to bring the message to others: “Get you up to a high mountain, O herald of good tidings to Zion; lift up your voice with strength, O herald of good tidings to Jerusalem” (40:9). All creation shares in the joy of salvation: “Sing for joy, O heavens, and exult, O earth! Break forth, O mountains, into singing! For the Lord has comforted his people, and will have compassion on his suffering ones” (49:13).
Zechariah, looking to the day of the Lord, invites the people to acclaim the king who comes “humble and riding on a donkey”: “Rejoice greatly, O daughter Zion! Shout aloud, O daughter Jerusalem! Lo, your king comes to you; triumphant and victorious is he” (9:9).
Perhaps the most exciting invitation is that of the prophet Zephaniah, who presents God with his people in the midst of a celebration overflowing with the joy of salvation. I find it thrilling to reread this text: “The Lord, your God is in your midst, a warrior who gives you the victory; he will rejoice over you with gladness, he will renew you in his love; he will exult over you with loud singing, as on a day of festival” (3:17).
This is the joy which we experience daily, amid the little things of life, as a response to the loving invitation of God our Father: “My child, treat yourself well, according to your means… Do not deprive yourself of the day’s enjoyment” (Sir 14:11, 14). What tender paternal love echoes in these words!
The Gospel, radiant with the glory of Christ’s cross, constantly invites us to rejoice. A few examples will suffice. “Rejoice!” is the angel’s greeting to Mary (Lk 1:28). Mary’s visit to Elizabeth makes John leap for joy in his mother’s womb (cf. Lk 1:41). In her song of praise, Mary proclaims: “My spirit rejoices in God my Saviour” (Lk 1:47). When Jesus begins his ministry, John cries out: “For this reason, my joy has been fulfilled” (Jn 3:29). Jesus himself “rejoiced in the Holy Spirit” (Lk 10:21). His message brings us joy: “I have said these things to you, so that my joy may be in you, and that your joy may be complete” (Jn 15:11). Our Christian joy drinks of the wellspring of his brimming heart. He promises his disciples: “You will be sorrowful, but your sorrow will turn into joy” (Jn 16:20). He then goes on to say: “But I will see you again and your hearts will rejoice, and no one will take your joy from you” (Jn 16:22). The disciples “rejoiced” (Jn 20:20) at the sight of the risen Christ. In the Acts of the Apostles we read that the first Christians “ate their food with glad and generous hearts” (2:46). Wherever the disciples went, “there was great joy” (8:8); even amid persecution they continued to be “filled with joy” (13:52). The newly baptized eunuch “went on his way rejoicing” (8:39), while Paul’s jailer “and his entire household rejoiced that he had become a believer in God” (16:34). Why should we not also enter into this great stream of joy?

Advent is a time of joyful waiting! Let us rejoice for the Lord is coming! He is here!
