My eyes have seen Your salvation

 Under Jewish Law a woman was required, after giving birth to a child, to offer to the Lord in sacrifice a lamb or two turtledoves or two young pigeons. Mary and Joseph, in bringing Jesus to the temple, fulfilled the prescribed legal requirement. At the same time they also consecrated Jesus to God: “you shall set apart to the Lord all that first opens the womb” (Exod. 13:12). In presenting Jesus, Mary and Joseph were returning to the Lord the very gift that he had given them. Their offering expressed the depth of their devotion and love of God.
 Simeon and Anna also gave God the worship of their hearts. The Spirit rested upon Simeon, preparing his heart for the Lord's coming and causing him to long to set his eyes on the Christ the Lord. Delighting in Jesus, he declared: “mine eyes have seen thy salvation which thou hast prepared in the presence of all peoples, a light for revelation to the Gentiles”. Similarly Anna was seeking the Lord. She had been in the temple for years, longing and praying for the Lord's coming. Now drawn by the Spirit she blessed Jesus.
 In Mary, Joseph, Simeon and Anna we see so much desire, longing and love for the Lord. They rejoiced as they recognized that Jesus was the longed-for Christ. It was the Holy Spirit who gave birth to this desire, longing, recognition and delight in their lives. The Spirit wants to give us a similar longing - no longer, of course, for the first coming of the Lord - but for his return. The Spirit wishes to purify our hearts from all dullness, indifference and apathy so that we may desire to see the light of Jesus' face and long to set our eyes on his glory when he comes again. By creating in our hearts this longing for and delight in Jesus, the Holy Spirit consoles and comforts us. St. Joseph the Worker Parish (excerpt: catholic-bible-school.org)
