God's design for human sexuality and marriage represents a transformative force that reshaped Roman society through Christian values. This design establishes marriage as heterosexual, monogamous, and lifelong, serving as the foundation for family and civilization. The biblical framework calls for both truth and love in addressing sexual matters, emphasizing the importance of standing firm in biblical principles while showing compassion. Christians are called to recognize that all sexual sin breaks God's will while maintaining a loving approach that doesn't compromise truth.
