EFN holds 21 cell groups in total. Cell groups vary each year. This is due to cell groups transforming into churches. Cell groups are established when a small group of people gather to worship in a certain area, usually in a new mission field. When a cell group grows in number the pastor later declares it as a church. This is why the number of EFN churches increase and the number of cell groups vary.
We are encouraged by Hebrews 10:24-25 as it says,
“And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.”
