In this sermon, Roydon Frost preaches from 1 Corinthians 1:1-9, drawing parallels between ancient Corinth and modern cities like Johannesburg to highlight the challenge of integrating the gospel into diverse, worldly cultures. He emphasizes the importance of Christians maintaining their distinctiveness and embracing sanctification in Christ while engaging with the world, advocating for a countercultural approach that offers an alternative way of life. Roydon Frost urges Christians to live out their unique identity and mission, stressing that they should not conform to worldly standards but instead be transformed by the gospel. By doing so, Christians can navigate the complexities of society while remaining true to their calling.
