"For the body is not one member, but many. If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body? And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body? If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling? But now hath God set the members every one of them in the body, as it hath pleased him. And if they were all one member, where were the body? But now are they many members, yet but one body. And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.Nay, much more those members of the body, which seem to be more feeble, are necessary: And those members of the body, which we think to be less honourable, upon these we bestow more abundant honour; and our uncomely parts have more abundant comeliness.For our comely parts have no need: but God hath tempered the body together, having given more abundant honour to that part which lacked.That there should be no schism in the body; but that the members should have the same care one for another."(1 Corinthians 12:14-25)
The verses below speaks about the parts of the body.All the parts of the body are created by GOD,it is the word of GOD that controls every part of the body.There is no other religious books in this world that speaks about the parts of the body.Here it is written that there is one body but there are many members.All these members will together hand in hand,the members of the body cannot be independant.If it is independent,the body cannot work.When GOD made human being,He made all the parts of the body to form a perfect human being.Without the members of the body,the body cannot function.Below is the picture of the human body.All the parts of the body are controlled by GOD,and it will work only by hearing respond from GOD's WORD. Why we have weakness in our body is because we have trangressed against the controller of the body which is the WORD OF GOD.
"And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee."(Exodus 15:26)
