Dear Stranger,
How do I know, it all rings true for me, the more I read, the more I learn, it all comes winging its way back to Christ, now you can accuse me of cherry picking, it could be my confirmation bias, sue me, it is true for me ( me ).
Oh and it works, you just have to practice, practice until it becomes second nature, I am still practising, one day I love my neighbour, the next I am thinking, wanker, I will take the bins out next week.
Gonnagle.
