The Napkin Test
Now, if your friend can take your notes on the back of that napkin and with the help of the Holy Spirit, do what you do, congratulations! You have a simple enough ministry to reproduce.
If you can’t write out everything your friend will need on that napkin, go back and simplify things. You might be making followers of Jesus, but they may not be able to pass on the complicated strategy that you have. This is why you don’t see seminaries popping up all over the place or Christian Television Stations multiplying. They’re too complicated.
Simple is reproducible. Reproducible spreads. If you want to see the Gospel spread, make sure you can explain how on the back of a napkin.
