undoing prejudice

It is really easy to get frustrated when road work or similar public works projects take longer than expected. But as I think about my home projects, especially building this climbing wall in my garage, it makes perfect sense. I've had my second three hour set of construction (with others helping of course) and progress is painfully slow. I'm not handy and this is more complicated than I thought it would be - yikes!
This kinda relates to the idea of prejudice but not really. Some it has to do with looking down on others as inept or "less," when I am lenient with myself when the same things happen. The reason prejudice is on my mind, is the sermon our pastor preached yesterday. James 2:1-4 talks about favoring the rich over the poor and when you look more intently at your life you can see all this preferential treatment that you extend to others, based on what you value. It is one thing to identify prejudice in your life and a whole other to root it out. I've been thinking as to how Jesus undoes the prejudices within us all. While a lot of things came to mind, here are the two big ones.
First, he undoes our need for prejudice. We look down on others to lift ourselves up. When we know the love Jesus has for us, despite being undeserving, we don't need to make our way up in the world by stepping on others. Second, he gives us a common object of love. When we are loved by God we love him in return. One of things that unites people is a common love. Random people in a football stadium can experience a deep sense of unity and oneness as the cheer for the same team. and a few things come to mind. Instead of loving ourselves, our position, our power, reputation, or all other sorts of things we love God and this love will unite us with all sorts of other people who love the same God.
