In Matthew 5:31-37, Jesus calls His followers to honor the covenant of marriage with faithfulness and integrity, teaching that divorce and oaths should not be treated lightly. This reflects the creation story in Genesis, where God joins man and woman together as one flesh, establishing marriage as a sacred bond. Just as Adam and Eve were united in pure trust and transparency, Jesus emphasizes truthfulness in words and commitments, instructing His listeners to let their "yes" mean "yes" and their "no" mean "no." This highlights the profound weight and sanctity of relationships designed by God, calling for respect and sincerity in living out His design.
