This sermon addresses the topic of sexual immorality and God's call for believers to live by a higher standard of holiness. Pastor Ricks emphasizes that while the world may rebel against God's sexual morality, Christians are called to be distinct and set apart. He explains that although we are under a new covenant of grace through Jesus Christ, God's moral expectations remain unchanged. The sermon encourages believers to embrace their identity in Christ, live from a position of holiness, and allow the Holy Spirit to empower them in living righteously.
