When Jesus admonished his disciples to forsake judgment he probably was noting that any criticism we make against others most always applies to us as well. When I note the inconsistencies of others, I simply remind myself of my own. When I see others "cherrypicking" the data to support their opinions, I can't deny doing the same. If I weren't a jerk on occasion, I probably wouldn't be so familiar with the defining characteristics.
In admitting how criticism and judgment cuts both ways, I have to ask myself why I spend even one minute looking for the faults in others. Of course, I think I know why. It's just a lot more fun to work on everyone else than it is to try to improve me.
