You quoted entirely different passages from the Matthew 13 I quoted from. In Matt. 13 the fruit isn't the "teaching." [And I don't necessarily agree that the fruit in the passages you refer to 'are the teachings' but that is another topic].
Your right. I'm sorry. I'm not so good at following the rules myself lately.
I just got done reading the Matthew 13 passage that you reffered to. It is very interesting. Let me honesty share what I see there, ok? I'm not good at going into long winded explanations so I'll just keep it simple. If you want me to I'll try to elaborate.
1. God plants the seed.
2. The seed is the teaching of the Kingdom message, the gospel, christianity.
3. The different types of soil are the hearts of the people who recieve the seed. Because of worry, fear, persecution etc the first 3 guys didn't bear fruit.
4. The fruit or lack of depends on whether of not the seed/teaching was understood when it was recieved.
5. The fruit grows and increases to different degrees when it is recieved in understanding.
6. The fruit is the promoting and spreading of the Kingdom message.
Previously in the chapter Jesus told His disciples that He spoke in parables because because He didn't want the people to automatically understand. He quotes Isaiah and explains that they couldn't understand because they were stubborn and held on to their preconcieved ideas and in essence rejected the truth.
I think this is why Jesus didn't just spell the message out for them. He wanted to give them the opportunity to humbly exercise their faith with an open mind.
My point is this. The passage is not about a person recieving the message of salvation and displaying evidence of that by bearing good works. It's about recieving the kingdom message with understanding despite external circimstances, in which that fruit is evidenced by the spreading of the kingdom message. The disciple were a good example of this. They spread the kingdom message against great odds, even unto death, and nothing grew as fast and/or as big ever.
That's the way I see it anyway.
