The readings for the Fifth Sunday of Lent have many levels of meaning, but ultimately they tell one thing: The glory of God is on the way for all those who choose Jesus as Lord and Savior.
In the first reading, God tells Ezekiel, "O my people, I will open your graves and have you rise from them, and bring you back to the land of Israel." Here God isn't speaking literally about the resurrection but rather that He will bring them back from captivity, and also bring them alive in the culture of Judaism.
On the second Sunday of Lent, the Church gives us the scene of Jesus, up on the mountain, being transfigured before Peter, James and John. The Church wants to lift our eyes to the beauty of our calling in Christ. Keeping our eyes fixed on Jesus' Transfiguration lifts our eyes above our present period of purification to allow Jesus to have a new freedom in our hearts. This prepares us for the glory as pre-figured in the Transfiguration.
