Revelation 1:20; The Seven Churches
Revelation 1:20 The mystery of the seven stars which thou sawest in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven candlesticks which thou sawest are the seven churches.
There are messengers sent to the seven churches with a message for each church. When we have an ailment, and we are experiencing some bodily discomfort we should go and consult a doctor to have our bodies examined so that we may know what has gone wrong with our health. You may have a family physician who has all your medical records and is able to look back at the medical records and make an assessment of your current ailment with the support of your past medical history. In this way, you would perhaps be able to know what has gone wrong.
However, you may also go for an annual medical check-up whereby you would be thoroughly checked from head to toe, with blood tests, X-rays and a medical report would be given to assess your physical health.
