John 19, 20, and 21

I was reading the Bible this morning and I turned to John 19 and started reading. I read through the rest of John because it was so good. I never really read any books of the Bible thoroughly save Matthew and Genesis. John was amazing. He said that Jesus did so many things that even the world itself could not contain the books that would be written. He also said that these things are written that we may believe in God, that we may find life in His name. It was pretty interesting. One thing that I didn’t understand too well though is the fact that Jesus told the disciple whom he loved to take care of his mother I think, and in later chapters he speaks of the disciple whom he loved also. But it says in the 21:20 that “The disciple whom Jesus loved following, who had also leaned on His breast at the supper, and said, “Lord who is the one who betrays you?” and then if you read up to the 24th verse it says “This is the disciple who testifies of these things, and wrote these things; and we know that his testimony is true” Was John the same disciple who took care of Mary? I don’t know. But it sure was interesting reading that chapter.
