Assumptions between a couple with reference to the Bible can vary depending on their individual beliefs and interpretations. However, some common assumptions may include the belief in the sanctity of marriage as emphasized in biblical teachings, the expectation of mutual respect and love, and the commitment to supporting and nurturing each other in accordance with biblical principles. This may also involve the assumption of shared values and the desire to live a life that aligns with biblical teachings, including fidelity, forgiveness, and the pursuit of righteousness. Ultimately, these assumptions form a foundation for the couple's shared commitment to building a strong, God-centered relationship.
