Rejection is what Jesus is all about. I think this Methodist article describes it pretty well.
I really like this Catholic youtube video of "Blessed are they".
Imagining being the pope and getting shot and forgiving the shooter.
I'm not at all there yet. I hope to get to a point where I know the message to speak to myself when I feel rejected to be thankful for the opportunity to be forgiving - really is that it ??? What should we be saying to ourselves? There is also the not being a doormat thing in meek. So, set expectations correctly up front, right?
