Wolfgang Simson keeps us up-to-date with the house church movement globally. Here is his latest summary:
"In total there are currently (mid 2021) at least 22.6 million house churches worldwide with a total of around 300 million members. They are, considering all internal and contextual factors, by far the most viral, adaptable and multipliable segment of Christ‐followers globally. If their number continues to grow at a very realistic rate of 20% per year, they will reach a membership of more than 4 billion people within the next 30 years – while most traditional church systems are in overall decline. This is why the author (Simson), in his publications called Starfish Vision and Starfish Manifesto, encourages all servants of Christ worldwide to work together to see half the population of the planet discipled in our lifetime (see Mt 24:39‐41) through the massive planting of house‐based Kingdom Communities."
