Today, and always, we Christians are all invited to share Jesus' joy. He, filled with the holy Spirit, said: «Father, Lord of heaven and earth, I praise you, because you have hidden these things from the wise and learned and revealed them to simple people» (Mt 11:25). Very rightly, this fragment of the Gospel has been called the “Magnificat of Jesus” by some authors, as the underlying idea is the same as in Mary's Canticle (cf. Lc 1:46-55).
Joy is an attitude which goes together with hope. It has to be difficult for a person who has no hope, to be happy. And, what is it that we Christians put our hope in? The coming of the Messiah and of his Kingdom, in which justice and peace will bloom; a new reality where «the wolf will dwell with the lamb, the leopard will rest beside the kid, the calf and the lion cub will lead them» (Is 11:6). The kingdom we are waiting for is making its way day by day, and we have to know how to discover its presence amongst us. For the world we live in, so lacking in peace and harmony, in justice and love, how necessary the hope of us Christians is! A hope that does not come from natural optimism nor false illusion, but from God himself.
However, Christian hope, which is light and heat for the world, will only be had by that ones who are simple and humble of heart, because God has hidden knowledge and the mystery of his kingdom's love from the wise and expert, that is to say, from the ones who are blinded by pride in their erudition.
A good way to prepare the paths of the Lord in this Advent would precisely be to grow in humility and in simplicity, to open our hearts to the gifts of God, to live with hope and become better witnesses of Jesus' kingdom every day.
