For optimal health it is essential that every part of a human body is working properly. And many people go for an annual physical check-up with their doctors to ensure that each part is working properly. EACH PART MUST BE WORKING PROPERLY. In addition, the JOINTS between each of the parts must be functioning properly. We are each parts of a Body. We are the parts that make up the Body of the Living Jesus Christ. As a part, am I working properly? In this period before Passover, we should be doing a lot of self examination and asking questions like this. And in answering the question, we will see that we must pay attention to the health of the part and the health of the joints.
