Take John Chapters 13,14 as one sweeping incident. After all that is what it is, and the chapter divisions can be such a hindrance at times. They are quite artificial and remember they were added many years after the Scriptures were written.
In John Chapter 14 at verse 6, Thomas is looking a bit worried. Right to the end Jesus said things that gave His disciples worried looks. Thomas is almost cheeky. You know where you are going but we don’t know where you are going so how can we know the way. Jesus is so lovingly patient.
If it were not for these words of Thomas we might never have had these famous words in verse 6. I am the way and the truth and the life – no man comes to the Father except through Me. You know the way because you know Me. I am the way. When you know me you know the way. These sentences know no parallel anywhere.
