This Advent sermon explores the theme of hope by examining Isaiah's prophecy about the coming Messiah. The pastor addresses how disappointment can signal misplaced hope and invites listeners to recenter their hope in Jesus Christ. The message emphasizes that we live in the "already and not yet" of God's kingdom—Jesus has come, bringing light into darkness, yet we still experience suffering and wait for His return. Hope is defined not as wishful thinking but as "the expectation of coming good based on the person and promises of God." The sermon encourages believers to practice hope by recognizing Jesus as Wonderful Counselor, Mighty God, Everlasting Father, and Prince of Peace, while actively participating in the advancement of God's kingdom through small acts of justice and mercy.
