Here is an excerpt:
If we’re honest, there are times where we meet a brother or sister in Christ and don’t feel like being a brother or sister in Christ to them. Sometimes the feeling is subtle and subversive–so subtle that we almost deny the feeling; yet we’ve allowed ourselves to be rubbed the wrong way by that person. It might be that they are more successful, attractive, intelligent, or just flat out better than you at everything they do. It could be that they accomplished all of this while displaying sinful characteristics in the process. We see sin in them more than we see the same in our self (Matthew 7:3) . Maybe they took something that we believed should’ve been ours. Perhaps it was a promotion or award at work. You know that they follow Christ, but boy, you wish they didn’t so that you wouldn’t feel so bad about giving them an earful.
