Been meaning to post this insightful exploration of John chapter 13. (Not entirely sure about the points made after the creative "story" bit, but still...)
I've been finding it more and more helpful to read or hear creative pieces like this - which imagine what it was like to be with the historical figures in the Bible, to hear what was said and feel what was felt, and particularly to focus on how messages were delivered, human to human.
Understanding, as Christians do, that the Lord Jesus really bore out dishonour, by dying in our place, so we do not have to die, the carefully phrased words he said to Peter really are incredible. They show his intention to serve sinners by setting them free from sin, making them "clean" (at the time Jewish cleanness meant being right with God, while being unclean meant being unfit to approach God).
Can it be that He would do this in love for us? Astoundingly, the rest of the Bible tells us it's not just for those following Him then, but for all who trust Him and seek to obey Him today. He went to death as a criminal, bruised and broken, and took onto Himself all the wrong we have done against God. What amazing love!
