"Life is one great object lesson"

Here I would like to mix a couple of Gospel principles. We have been placed on Earth to gain intelligence and to grow. Doctrine and Covenants 130:18-19 states

18 Whatever principle of intelligence we attain unto in this life, it will rise with us in the resurrection.19 And if a person gains more knowledge and intelligence in this life through his diligence and obedience than another, he will have so much the advantage in the world to come.

Now President Maeser teaches us that everything in life is an object lesson. Therefore the different parts of our body and their functions are symbolic of eternal principles that we are to learn. Quite frequently the scriptures use parts of the body to represent spiritual aspects. Phrases like "broken heart", "arm of salvation", "ears to hear and eyes to see", are all examples of spiritual principles that God uses parts of our body to help us understand. With what we have learned in anatomy, and the functions of the body, I hope we all can appreciate and understand just how miraculous the body is, and also learn the gospel principles that we are supposed to learn from those metaphors. Everything we learn now, we be that much better for us in the future.
