Yes, people do not seem to want to know God. They can tell you all they know about the subject in five words or less. For me all the books in the world would not be enough to talk about what God has done. People ask questions that would take a whole book to explain. So I just try to give them a summery of what that book would say.
And there are also many other things which Jesus did, which if they were recorded one by one, I suppose that even the
world itself could not contain the
books.
This verse, found in John 21:25 of the Bible, means that Jesus performed so many acts and said so many things during his ministry that if every single detail was written down, the resulting collection of books would be so vast that there wouldn't be enough space in the world to store them all; essentially signifying the immensity and fullness of Jesus' life and teachings that cannot be fully captured in a single written record.
