Accurate Comparison?

Thoughts from random conversations recently:

An Olympic athlete will train for their sport and put themselves on a strict regimen. A wrestler or weightlifter may be on a high carb diet but a cyclist or a swimmer would be more on a low-carb diet. When asked why they eat the way they do, they will both give the same answer, "because I'm in training."

I've never heard of anyone questioning a cyclist saying they should eat more carbs or tell a weightlifter their diet is incorrect. People tend to have for respect for them and to trust that the athlete has done the research for their particular Sport and event and know what they're doing.

In a similar way all Christians don't work in the same exact field or the same exact capacity. One needs to hone a different set of skills than another so that they can be effective in the different areas where they live or where they're called. So if one is ministering to a certain demographic of people they would need to have some idea of the things that those kinds of people are into and order to relate to that. And some other areas there would be no need for any knowledge in that Arena.

However, a Christian seems quick to judge if another Christian is "eating carbs" when it's different from what he is doing. We have this respect for athletes but we don't seem to have it for fellow Christians. In areas that are clearly black and white -- such as murder -- there is no room for differences, but in areas that are gray we should resist the tendency to be judgmental.
