The key word in today's readings is "Prepare". A note of expectation runs through all three readings, and preparation becomes a must. In the passage from Baruch, Jerusalem is in mourning for the destruction of the Temple and her children in exile. However, here Jerusalem is told to expect the return of her children in triumph and she is to prepare for this by "putting on the glory of God for ever" (Bar.5:1), and her resplendence will be a reflection of the glory of God.

This note of waiting in hope and expectation is repeated by Paul in his message to the Philippians, telling them to prepare for "the Day of Christ when you will reach the perfect goodness which Jesus Christ produces in us for the glory and praise of God." (Phil. 1:11).

Again, in Luke's account of John's preaching, he quotes from Isaiah all the steps taken "to prepare a way for the Lord" so that "all humankind shall see the salvation of God." (Lk. 3:6). For this much needs to be done, but as Baruch mentions, "God will guide Israel by the light of His glory, with His mercy and integrity for escort." (Bar. 5:9).

All the preparation is needed because of the obstacles along the way to salvation, but God walks alongside to remove the hindrances. As Paul says, "the One who began this work in you will see it is finished when the Day of Jesus Christ comes." (Phil.1:6).
