How do we know God's design for marriage is important?

God's design for marriage is crucial because it mirrors the sacred covenant He has with His people. In Matthew 19, Jesus underscores that marriage is a divine institution meant to be lifelong. The unity of husband and wife reflects God’s faithfulness to His own creation. When we understand marriage as God’s intended order, we see its role in promoting stability, love, and understanding within families, which aligns with God's overarching plan for human relationships and society as a whole.
