In Advent, the liturgy frequently repeats and assures us, as if to overcome our natural diffidence, that God ‘’comes’’: He comes to be with us in every situation of ours, He comes to dwell among us, to live with us and within us; He comes to fill the gaps that divide and separate us; He comes to reconcile us with Him and with one another. He comes into human history to knock at the door of every man and woman of good will, to bring to individuals, families and peoples the gifts of brotherhood, harmony and peace. This is why Advent is par excellence the season of hope in which believers in Christ are invited to remain in watchful and active waiting, nourished by prayer and the effective commitment to love.

(Pope Benedict XVI)
