In God's eyes, is gluttony just as bad a sin as any other?

Two points:

1. God places lying in the same category as murder.

2. The below verses give us an understanding:

And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares. For as a snare shall it come on all them that dwell on the face of the whole earth. Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.

(Luke 21:34-36)

"Surfeiting" is over-excess, and is a word used for over-eating, but specifically it means over-indulgence in anything.

I don't see it in the 10 Commandments, nor did Christ talk about it in the Sermon on the Mount. From my experience it appears that the "seriousness" of a sin is related to the amount of damage it can do in a person's life. Gluttony is not as serious as other sins.

Interesting, I was listening to 2 sermons on fasting this morning.

Yes, gluttony is a sin of the flesh.

God’s Word condemns both drunkenness and gluttony as behavior that is incompatible with serving God. Therefore, the Christian congregation regards a confirmed glutton in the same manner as it views a habitual drunkard. Neither a drunkard nor a glutton can be part of the Christian congregation.

Proverbs 23:20, 21 states: “Do not come to be among heavy drinkers of wine, among those who are gluttonous eaters of flesh. For a drunkard and a glutton will come to poverty, and drowsiness will clothe one with mere rags.”

At Deuteronomy 21:20, we read about a “stubborn and rebellious” individual, who deserved to be put to death under the Mosaic Law. According to this verse, two characteristics of that rebellious and unrepentant individual were that he was “a glutton and a drunkard.” Clearly, in ancient Israel, gluttony was viewed as an unacceptable practice for those who desired to serve God.

Yes a sin is a sin and if any sin done on purpose without trying to be corrected will not be forgiven.

“Sin lies only in hurting other people unnecessarily. All other "sins" are invented nonsense. (Hurting yourself is not sinful - just stupid).”

Robert A. Heinlein (American science-fiction Writer, 1907-1988)
