Jesus says in Matthew 22:38-39, "this is the first and greatest commandment. And the second is like unto it, Thou shall love thy neighbor as thyself."
If we are to be fishers of men we need to love our neighbor as we love ourselves. Jesus didn't just mean literal neighbors, but I believe He meant everyone. Think about how you would treat yourself in certain situations. Let's take forgiveness for example. If you did something wrong, wouldn't you forgive you? Now if someone else does the exact thing you did, why wouldn't you forgive them? If you don't, are you loving your neighbor as you do yourself?
Something I saw working in a restaurant, by some who worked in the kitchen, was that sometimes food would be dropped on the floor (by accident) and then they served it. I tried to pick up anything off the floor myself and quickly throw it out to avoid arguments, but when I didn't I would suggest to the one who picked it up (usually the manager would be the one to pick it up) that if they wouldn't eat it, why would they serve it? Think about it, if it was too gross for them to eat it, why would they serve it?
I think you get my point. If you have any examples of how we can love our neighbors as our selves or stories similar to mine above, please share it by writing a comment. Also before you leave check out this weeks verse which is entitled Be Not Ashamed.
