A human being is comprised of many organs positioned in his/her body and each organ has his own functions and responsibilities to perform with specialties. No other organ can replace the functions of other except in certain circumstances.
If we have a 100% believe that all organs are the property of God and it is his gift to us then we are also responsible to use all organs of the body in a wise way and as being ordered by him. But the story is different, we are negating the orders.
- Stomach: we eat unhealthy food, excessive food then required etc
- Kidneys: Either fill with excessive water or with no water, destroy it with blood pressure or sugar problem
- Hands: make them work in a positive way or use them to punch any one’s face
- Tongue: we use it making friends or foe, can built honors for others or can destroy, can take revenge and may defend someone in a worst ways etc
God has given us full authority to use organs in a better way as per his will or make its life shorter then normal.
