There is no perfect human being on planet earth, don't ever expect a perfect marriage from any relationship, even though an angel metamorphose to human being and engage in marriage the imperfection will be undoubtedly display. Sun-shine, moon-shine and celestial angel are not even clean in the sight of Divinity.
God created human being imperfect, don't expect too much in any relationship with any human being, and make sure you give any person benefit of doubt during the pleasant moment.
You don't quash your marriage with physical object. You don't quash crises in your marriage with ignorant, rivalry or comparison, humility and application of godly information, with surrender tactics will become weapon to quash the crisis.
