From Stormie O'Martian's Power of a Praying Wife...
"Lord, I pray that You would strengthen my husband to resist any temptation that comes his way. Deliver him from evils such as adultery, pornography, drugs, alcohol, gambling, and perversion. Remove temptation especially in the area of (name of specific temptation).
Make him strong where he is weak. Help him to rise above anything that seeks to erect a stronghold in his life. Lord, You've said that "whoever has no rule over his own spirit is like a city broken down, without walls' (Proverbs 25:28).
I pray that (husband's name) will not be broken down by the power of evil, but raised up by the power of God. Help him to take charge over his own spirit and have self-control to resist anything and anyone who becomes a temptation.
No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it. 1 Corinthians 10:13"
