No doubt, Martin Luther was greatly James-3 cursed for standing up to the abuses and false doctrines of the church of his day. His boldness impressed me when I watched the movie about his life in grade school.
Here, he talks about his struggle to get free of demonic temptation; though, sadly, he ended up in life cursing people back!
James 4:7 — “Therefore submit to God. Resist the devil and he will flee from you.”

“Just when you feel that temptation is strongest
and you are most unprepared to pray,
then go to a place where you are alone,
and pray the Lord’s Prayer
and whatever you can possibly say
against Satan and his temptation.
Then you will feel that the temptation becomes less severe
and that Satan takes flight.”
