Hmmmmm. Interesting folks. Glad to hear it's restated elsewhere as well.
Regardless, I'd like to add the observation that whether or not it is correctly included in Matthew, LutheranGirl, perhaps the important point is that the content of the verse is TRUE!
There ARE evil spirits that resist the simple lawful command to leave made by a born again Christian. And however the spiritual or physical mechanism works, adding fasting to our prayer DOES increase the power of our commands in the spiritual world much like adding a power steering mechanism does to the steering wheel of your vehicle. And ultimately, they do have to go.
Since that is the case, it makes perfect sense that the adversary seeks to keep us from praying or fasting either one, but ESPECIALLY from fasting. Even to discrediting the scriptural concepts. Guess he doen't mind if we pray prayers of frustration and fear and despair, so long as we don't get the power to make them prayers of hope, authority, and command!
Screw him! Let's FAST and pray!
PS: Gotta be Biblical about my statements, of course ... *grin*
2Chron 7:14, "If My people who are called by My name will humble themselves, and pray and seek my face, and turn from their wicked ways, then will I hear from heaven, and will forgive their sin and heal their land."
That's all understandable to me except the "humble themselves part. How do we do THAT? By fasting!
Psalm 35:13 "... I humbled myself with fasting."
