Intersession

Because we have been made one flesh, we can intercede for our spouse like no other. We can resist the devil on their behalf, and bring turth where there are lies. Bring light to the darkness. God's Word promises that satan will flee, and the stronghold will be broken.

...But as for me and my household, we will serve the LORD.
Joshua 24:15

Submit yourselves, then, to God. Resist the devil, and he will flee from you. Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded.
James 4:7-8

My brothers, if one of you should wander from the truth and someone should bring him back, remember this: Whoever turns a sinner from the error of his way will save him from death and cover over a multitude of sins.
James 5:19-20
