What is the greatest threat to Christianity in this century?

Summary

The sermon argues that the greatest contemporary threat to Christianity is not external ideologies like Islam, but rather "Christendom" itself, which dilutes the Gospel, and a prevalent postmodern skepticism about objective truth. Key subjects include the historical facts of Jesus' birth, death, and resurrection, as well as Calvin's emphasis on the Reformation stemming from a corrupt worship and a proper view of God. The practical takeaway is the urgent need for believers to assert the factual basis of the Gospel and to maintain a reverent and accurate understanding of God amidst societal doubt.
