I’ll return to John 6 later in the sequence – possibly more than once – but we had these this morning, and I’m slipping behind due to pressure of work! (I hope to return to Stark tomorrow as well)

66 From this time many of his disciples turned back and no longer followed him.
67 You do not want to leave too, do you? Jesus asked the Twelve.
68 Simon Peter answered him, Lord, to whom shall we go? You have the words of eternal life.

Why is this a favourite passage?

Verse 66: I find this an incredibly poignant verse. People who had been following Jesus, who had seen the signs he has performed, now abandon the way because the teaching had become too hard to absorb – the teaching about the Eucharist (on which more another time, but see here).
Verse 67: more poignancy, and here it is essential that we hold on to the humanity of Jesus, rather than simply reading it as a divine challenge, otherwise the implicit loneliness is lost (the loneliness will come, but not yet).
Verse 68: those who remain, who have accepted the teaching and entered into the life, recognise Jesus for who he is and what he conveys. This is one of several basic Christian confessions in Scripture, but in my view, one of the best.
