You don't really know what Jesus said, you know quotes from Jesus by the Apostles in their teachings.
1. Quite irrelevant to the topic, argument.
2. Humanism, as you attribute the authorship, and "responsibility" of the giving/preservation of the words in the book, including the Lord Jesus Christ, to men, not the LORD God.
3.Acts 20:35 KJV I have shewed you all things, how that so labouring ye ought to support the weak, and to
remember the words of the Lord Jesus, how he said, It is more blessed to give than to receive.
Show us, chapter, verse, where the Lord Jesus Christ ever said, these words:
It is more blessed to give than to receive.
Show us your "stuff."
How did Paul know that? No speculation-scripture.
