Once-Christian nations like Syria, Turkey, Egypt, and Lebanon drifted from faith due to conquests, economic pressures, persecution, emigration, and demographic shifts. The U.S., with its Christian heritage, risks a similar path through secularization and cultural drift. Pew Research shows Christian identification dropped from 77% to 65% in a decade. Scripture, like Judges 2:10 and Ephesians 6:13, warns against forgetting God and urges steadfastness. As a remnant (Romans 11:4), American Christians must engage in church, teach the faith, and resist modern “idols” (1 John 5:21) to preserve our covenant and avoid the Middle East’s fate.
