Paul addresses the deep division between Jews and Gentiles in Ephesus, showing how Christ transforms alienation into belonging. Everyone experiences alienation in marriage, work, school, or church, but Jesus bridges these divides through His blood. The Gentiles were once separated from Christ, alienated from God's people, and without hope. However, Christ's sacrifice creates covenant bonds stronger than family ties, bringing the far near and making strangers into family. While we should separate from worldly values and toxic influences, we must never alienate others but instead create welcoming communities where people feel loved while being challenged to grow.
