“I tell you that this man, rather than the other, went home justified before God. For all those who exalt themselves will be humbled, and those who humble themselves will be exalted.” Luke 18:9-14
It seems that self righteousness is just as a big problem today among secular people as it was in Jesus' day among religious people. People feel they are better than others if they are vegan, or vote against Trump or install solar panels or recycle or have the self control to never say or do anything inappropriate. I am not saying any of these things is bad in itself, but really it is not admirable to be someone who thinks he or she is better than someone else because of some selected behaviour. In other ways the people who are looked down on may have their own virtues - they may be the sort of people who tackle terrorists with shopping carts for example, or place themselves in danger to keep others safe - as we have seen several examples of recently in Australia and the USA.
So perhaps modern people would be wise to heed the teachings of Jesus in this respect? Specifically that humility is the highest virtue. That everything else you do counts for little if you do not have humility, and that in God's eyes the humble 'sinner' (i.e non-vegan, Trump voter, etc) is greater than someone who has done everything 'right' - if they have humility.
