The nucleus is the control center of the cells since it contains the genetic material. DNA which determines the characteristics of a cell and directs the production of proteins.
Cells may group together and form multicellular organisms. In most organisms, groups of tissues organize and work together to perform a common function. The structural and functional unit formed is called an organ.
Organs do not function independently. They also work as group. This group of organs is called an organ system.
If one of the organ system fails to function, what might happen to one's body? Of course, it will not work well.
Like the organ system, the body parts must also work together to perform varied activities which are useful and pleasing to God.
What did the "microscope of life" tell on this? According to I Corinthians 12:14-20, " For the body is not one member, but many It the foot shall say, Because I am not the hand, I am not of the body: it is therefore not of the body? And if the ear shall say, Because I am not the eye, I am not of the body: it is therefore not of the body? If the whole were hearing, where were the smelling? And if they were all one member, where were the body. But now are they many members, yet but one body."
Furthermore it really implies that just like the organs system that needs to work together, each body part must also do the same. God created our body with cells, that form an organ. These organs work in an organ system that might affect one another if one of them fails to function correctly.
Therefore, I must say that in the organ system all parts function together for good. The same is true with our life experience, despite of all the troubles, pains and suffering that we are dealing everyday, always hold on to this very meaningful verse " ALL THINGS WORK TOGETHER FOR GOODS ". We might not notice it because we are deceived by our thoughts but God knows what's best for us because He is the control center of our life just like what nucleus of the cell does to our body.
