The body is the handmaid of the soul ( St. Seraphim of Sarov )

The body is the handmaid of the soul, and the soul — its queen. Therefore it often happens that by the mercy of God our body is debilitated by illnesses. Passions weaken because of illnesses, and the person becomes well. Sometimes bodily illness itself is born of passions. To bear illness with patience and gratitude is regarded as a feat, and even more than one.
