In today’s First Reading those who remained faithful to the Lord despite all the persecution and calamity now sing his praises. The Song of Moses refers to the song the Israelites sung when they were delivered from destruction by the Egyptians due to the parting and crossing of the Red Sea (Exodus 15:1–21; see Exodus 14:19-31). Christ, the New Moses, has also led them through calamity and persecution into the Promised Land. It’s the moment of victory at the end of time when evil is definitively overthrown.
As part of the faithful’s song they rejoice that the Lord’s “righteous acts have been revealed.” At the end we will see completely how good and righteous Our Lord is. We may not see it clearly in this life, afflicted by suffering and evil, but we must trust and believe in it and it will be revealed one day for all to see.
We’ve already been delivered from evil through Baptism: the crossing of the waters of the Red Sea is a prefiguration of the salvation that comes through the water of Baptism. Let’s live in hope that the victory one day will be complete.
