Acts 2:46-47a “And day by day, continuing steadfastly with one accord in the temple and breaking bread from house to house, they partook of their food with exultation and simplicity of heart, praising God and having grace with all the people.”
When the church was established, three thousand people were saved, and later five thousand men were baptized (v. 41; 4:4). Altogether, at least eight thousand people received salvation. How did they live the church life? The church met together, but how did this many people meet? In other words, what was the foundation of their meetings? With anything that we do, there is always a foundation. Even language has a foundation. The twenty-six letters of the English alphabet are the foundation of the English language. What is the foundation of the church meetings? The eight thousand who were saved met in the temple and from house to house, from one house to another (2:46; 5:42). When they were in the temple, mainly Peter, John, and the other apostles spoke. But there was no way for Peter and John to meet with all eight thousand people, comprising a minimum of a thousand homes; the believers needed to meet from house to house.
Acts 5:42 says, “Every day, in the temple and from house to house, they did not cease teaching and announcing the gospel of Jesus as the Christ.” Those who were saved for even a day or two began to meet in their homes, and they did not speak the teachings of Moses or Elijah. Every household was speaking what they heard from Peter in the temple.
The crucial point is that the meetings in the homes were the foundation of the church meetings. A big meeting in the temple was not the foundation. The believers who were produced by the speaking in the temple were brought to meetings in individual homes. In other words, the building up of the church did not depend on the big meetings in the temple; rather, the building up of the church depended on the meetings in the homes, the meetings from house to house.
