let us walk in the light of the Lord.
The sun never gets very high in the sky these days. Advent brings late sunrises and early dusk, and 'the light of the Lord' in this verse from Isaiah reminds me of the warm light that glows in windows in the early evening. It beckons, and promises comfort.
But that isn't all, is it? Advent is a penitential season, a time of preparing our hearts for the Lord's appearing. Walking in the light of the Lord means transparent honesty as well as safety, letting the Holy Spirit search our minds and hearts, dispelling the darkness in which I, at least, often hide. There is no room for despair in Advent, no room for sin.
I needed to be inspired by St Francis Xavier today. I breathed a sigh of contentment and relief as I noted that it was his feast day today. He gave his life, spending it in preaching the Gospel and bringing the light of Christ to the nations. And as I remember him today, that same light falls on me as well. Let me walk in that light always.
