Can somebody tell me, what in the world does a tree bringing forth good (or bad) fruit have to do with the fruit of the Spirit?
Why is it when someone quotes Matthew 7:15-20 or Matthew 12:33, they automatically jump ship to Galatians to define what constitutes good fruit?
Matthew 7:15-23
“Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves. You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they? So every good tree bears good fruit, but the bad tree bears bad fruit. A good tree cannot produce bad fruit, nor can a bad tree produce good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. So then, you will know them by their fruits."
It's pretty clear that Jesus was warning about false prophets, and the WORDS they speak, leading people astray.
How about.....
Matthew 12:33-37
“Either make the tree good and its fruit good, or make the tree bad and its fruit bad; for the tree is known by its fruit. You brood of vipers, how can you, being evil, SPEAK what is good? For the mouth speaks out of that which fills the heart. The good man brings out of his good treasure what is good; and the evil man brings out of his evil treasure what is evil. But I tell you that every careless word that people speak, they shall give an accounting for it in the day of judgment. For by your words you will be justified, and by your words you will be condemned.”
Yeah. Once again, the good and bad fruit is referring to the WORDS one would speak. Namely, about Jesus Christ and who He is - Beelzebul or the Son of God?
It doesn't have anything to do with behavior, Galatians 5, or anything of the sort.
Incidentally, the word translated "bad" (Gr. sapros - literally "rotten") is used in Ephesians 4:29...
"Let no unwholesome WORD proceed from your mouth, but only such a word as is good for edification according to the need of the moment, so that it will give grace to those who hear."
So this rotten speach Paul mentioned is contrasted against words of edification.
And aside from Matthew 13:48, where Jesus used "sapros" in reference to fish, every NT instance is in reference to words. Only 8 uses of this word in the NT:
Matt 7:17,18
Matt 12:33 (twice)
Matt 13:48
Luke 6:43 (twice)
Eph 4:29
So bad fruit is rotten speech, false teachings, etc.,
Good fruit is sound doctrine and edifying speech. It most certainly has nothing to do with Galatians 5
