It strikes me that John 8:12-59 neatly illuminates the message of Galatians 5:15:
“If you bite and devour each other, watch out or you
will be destroyed by each other.” Galatians 5:15 NIV
The people bite and devour and Jesus warns them of such behaviour. Israel has received its Saviour and yet is blind.
The biting and devouring behaviour of the people is depicted throughout the verses. There is speculation by the people of Christ’s suicide (verse 22), that Christ is a Samaritan – that is a mongrel half-caste – in verse 48 and that Christ is demon-possessed (also, verse 48). The people proudly claim themselves to be Abraham’s children (verse 39) yet do not benefit Christ himself that claim.
Jesus responds to such biting and devouring by escaping the people’s grasp (verse 20 and 59) and by warning them that their ways will bring their destruction (verse 51).
It is not without reason that Paul precedes the warning about biting and devouring with Galatians 5:14. Galatians 5:14 reminds us to “Love your neighbour as yourself”!
