"Neither the husband nor the wife should merge his or her individuality in that of the other. Each has a personal relation to God. Of Him each is to ask, “What is right?” “What is wrong?” “How may I best fulfill life's purpose?” Let the wealth of your affection flow forth to Him who gave His life for you. Make Christ first and last and best in everything. As your love for Him becomes deeper and stronger, your love for each other will be purified and strengthened. MH 361.3"
"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you."
EGW directly applies the principle of prioritizing God (Christ) above all else, including the marital relationship. This is a clear echo of Matthew 6:33, which commands seeking God's kingdom first.
"Neither the husband nor the wife should attempt to exercise over the other an arbitrary control. Do not try to compel each other to yield to your wishes. You cannot do this and retain each other's love. Be kind, patient, and forbearing, considerate, and courteous. By the grace of God you can succeed in making each other happy, as in your marriage vow you promised to do. MH 361.5"
"Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,"
Both passages emphasize kindness, patience, and consideration in relationships, aligning with the characteristics of love described in 1 Corinthians 13:4.
