"You will know them by their fruits."
I think a lot of people think this means they will have the Fruit of the Spirit, but I have also heard that the Fruit is Good Doctrine as well.
Looking for your interpretations of these verses.
We all know that the only good way to understand is to be reading fully, getting all the context.
Let's think on that a moment. It's really reading fully through with listening. If a person reads just trying to see a doctrine, then they will hear only their doctrine, because they are closing their ears to listening to Christ, putting the doctrine above His Words.
Listening is the key, and to more than only this question. Listening is, we read here in this chapter,
part of what He tells us to do also!
So, chapter 7 as a whole does have one theme that is repeated several ways. And that will help a lot, listening to the entire chapter as a whole, I think. Verses 24-27, stating such a dramatic and powerful thing, are not alone in the chapter, but they are connecting to many things in the chapter. (as we could expect)
Christ words are so wonderful in that way: that if we read them again, even for a 4th or 10th time (!), we can learn new, invaluable things from Him.
Another very powerful passage to help also on fruits, to help us know what is good fruit, is in John chapter 15.
Altogether, I feel to really know well, one needs to read fully through the gospels. Else one might think something is only an interpretation. If I just answered this question very simply and directly, how would anyone know I was giving the true answer?
Only if they read fully through the gospels could they really know what is a true answer. No man, no doctrine, is ever a substitute for that full listening.
And...that full listening is what we need, and every doctrine falls short compared to that full listening to all that Christ says to us.
So, by the time you finish reading the Gospel of John and the Gospel of Matthew fully, you will probably have a pretty good understanding of what is "good fruit", even if you hadn't seen Galatians chapter 5 ever.
