This sermon opens the Advent season, a time when Christians celebrate Christ’s first coming and long for His return. Using Mary’s song in Luke 1:46–55, Pastor Chad shows three truths revealed in the “first Christmas carol.” (1) God is good and merciful: Mary, a poor and unknown girl from Nazareth, is overwhelmed that God sees her, chooses her, and transforms her from the inside out. Her song springs from reflecting on what heaven has declared over her—blessing, favor, and mercy. (2) God is great and just: Mary praises the Mighty One who fights for the humble, the hungry, and those who fear Him, while opposing the proud, powerful, and self-reliant. God overturns worldly values and lifts up those the world overlooks. (3) God is faithful: Mary celebrates the God who keeps His promises to Abraham and to generations after him. Advent reminds believers to rejoice in what Christ has done and to long with hope for His return, when His mercy, justice, and faithfulness will be fully revealed.
