This sermon reframes Reformation Sunday as a battle rather than a celebration, urging believers to reject complacency and defend the true gospel and orthodox confession against attacks from within and without.

Drawing on Psalm 46, the preacher presents Christ as the warrior-king whose victory guarantees the church’s ultimate safety, while calling Christians to participate in the struggle through repentance, faithful vocations, and the means of grace (baptism and the Lord’s Supper).

The message is an urgent call to action — preserve and pass on the confessional faith, hold the line even at cost, and trust the peace of God as you fight for the next generation of the church.
