And if one member suffers, all the members suffer with it; or if one member is honored, all the members rejoice with it.
Now you are the body of Christ, and members individually."
1 Corinthians 12:25-27 (NKJV)
Having your luggage lost when you travel is something you never want to have happen. One time, when I arrived at my destination, my bag was not there. When I talked to the people from the airline about this, they said it would not be easy to locate my bag, because the baggage system and the reservation system did not "talk to each other", there was a communication failure. That was a bit of a surprise to me, since the systems were a part of the same airline, but fortunately, my bag did arrive a few hours later.
After my experience with the lost bag, I was thinking about what Paul said in 1 Corinthians 12. Paul compared the body of Christ to our natural body. There should not be divisions in the body, and if one part of the body suffers or rejoices, the whole body either suffers or rejoices. This is talking about unity within the body of Christ, and just like our natural body, if some parts are not working together, if there is a communication failure, there will be problems.
Unfortunately, there are times when Christians have trouble working with one another. No matter what group a believer may be a part of, we are all a part of the body of Christ. We must work together to reach the lost and preach the Gospel around the world. Instead of working to build our own kingdom, we need to work together to build God's Kingdom and do His will. It should never be that various Christian groups and believers don't get along or work with one another. That kind of communication failure is unacceptable.
