1 Corinthians 12:26 (Amplified Bible)
There is a saying that goes something like, "The whole is greater (or more) than the sum of its parts". The idea is that things working together produce or become something greater than what they are individually. This saying expresses an important truth that we also see in the Bible, but there is something else we can see here if we look at this phrase a little bit differently. The whole is no greater than the sum of its parts when every part of that whole is not functioning properly.
Usually the whole cannot rise above the sum of the parts involved. In other words, you can have a very healthy and strong group that is restricted from its fullest potential by one or more weak member. There may be a company that is excelling in most of what it does but the parts that are not excelling are hindering the whole from moving forward. A church may have several areas that are working well but if there are some areas that are weak and struggling it will have an effect on the whole church. As Paul wrote in 1 Corinthians 12:26 when one part of the body is suffering the whole body is affected. The Body of Christ and organizations are made up of many parts; just think, what could happen if every part was doing well in their particular area?
