Strangers in the House of God

The sermon centers on the urgent need to guard the church against spiritual and cultural infiltration, drawing from John 10's imagery of the Good Shepherd and the stranger who enters by climbing over the wall. It warns that false teachers, ideological infiltrators, and moral relativism—particularly in the realms of gender, sexuality, and national identity—are not external threats but internal dangers that undermine biblical truth and the purity of the church. Using Romans 1 and Jude as foundational texts, the preacher argues that the faith once delivered must be defended with conviction, rejecting compromise and calling believers to discernment, spiritual vigilance, and active resistance to those who seek to scatter the flock. The message is both pastoral and prophetic, urging the congregation to stand firm in the Word, protect the church as God's bride, and remain watchful against enemies who come disguised as friends, whether in the pulpit, the classroom, or the home.
