A parable for Church Life that will endure any pandemic and ensure the future growth of the church by Apostle Aje Pelser, preached for HRC Cape Town 31st May, 2020

Medical introduction by Dr Stefan Wever

When Apostle Paul wrote that he taught publicly and from house to house in Acts 20:20, the early church was facing unprecedented challenges. As we enter a new phase of church, our challenges are different but the functions of the church cell remain the same.

Cells are the smallest structural unit containing all the fundamentals molecules of life and of which all living things are composed. As cells mature they specialize and become the building blocks for larger multicellular organisms such as humans. Although cells are much larger than atoms they are still extremely small. It would require about 10,000 human cells to cover the head of a pin. Every human being contains more than 30,000,000,000,000 cells.

The principal structures of a human cell and their functions:

1. Cell membrane: A double layered membrane enclosing the cell’s contents. It regulates passage of molecules in and out of the cell.

2. The cytoplasm of the cell contains all the specialized structures within the cell. It is the fluid within the cell.

3. Nucleus: The two main function of the cell nucleus is: storage of the hereditary material in the form of DNA and managing cellular function i.e. growth, metabolism, protein synthesis, reproduction. Within the nucleus are the following structures:

a. Nucleolus: Membrane-less organelle produces ribosomes (the cell’s protein producing structures).
b. Nuclear envelope: double layered membrane enclosing the contents of the nucleus. The envelope is perforated by tiny holes called nuclear pores that allows passage of molecules between the nucleus and the cytoplasm.
c. Chromatin and Chromosomes: Chromatin is packaged DNA to ensure that the DNA (3meters in length if uncoiled) fits into the nucleus. Chromatin fibers are further coiled and condensed to form chromosomes.

4. Endoplasmic Reticulum: Network of sacs acts as a pipeline between the nucleus and the cytoplasm. Ensures transportation of materials throughout the cell.

5. Golgi apparatus: Processes and packages the cell’s chemical products (built up in the endoplasmic reticulum) to be released from the cell.

6. Mitochondria: Supplies energy to the cell by using oxygen and nutrients.

7. Ribosomes: the sites for protein synthesis are found adhered to the Endoplasmic Reticulum or free in the Cytoplasm. These proteins are for the cells own use as well as to be transported outside the cell. These proteins include enzymes, hormones and neurotransmitters functioning as the major communication vehicle in the body including the brain, GIT, growth, repair, muscle function etc

8. Lysosomes are microbodies containing digestive enzymes to break down cellular waste products. These waste products are then used as new cell-building materials.

9. Peroxisomes are also microbodies that detoxify dangerous substances within the cell.

Let’s apply functions of a human cell to a household church group or home cell, and see how those functions will build the local body of believer up!

Spiritual applications of the functions of a cell to build the church:

1. The Door – cell membrane – regulates passage of molecules IN & OUT. Jesus is the door – filter everything through Him and His work on the cross. Jo
