Be watchful and prayerful! Certain marital problems are a result of spiritual attacks. The devil can instigate one partner against the other or use anyone at all.
“He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.” – Psalm 91: 1
“Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.” – Ephesians 6: 10-12
“Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.” – 1Peter 5: 8
