4:32 one soul. “One soul” connotes a common spirit of enthusiasm for the job at hand.

4:32 all things common. “Common” in the Greek means simply “ordinary.” Some believers (e.g., Barnabas—Acts 4:36-37) were well to do, but considered their possessions as just common goods which could easily be given up. This was not an early example of socialism or communism, as some teach, for it was entirely voluntary, not planned and enforced governmentally. They did not give up their possessions except as needed, but were quite willing to do so. Furthermore, this was done because of the special circumstances at the time and was not the practice among other churches. We should always be willing to share as needed, but this does not normally entail turning all possessions over to the church leaders.

4:33 witness of the resurrection. The apostles could witness “with great power” because they had seen the irrefutable evidence of the bodily resurrection of Christ. This is the crowning proof of the truth of Christianity. Only God Himself could defeat death, and Jesus had thereby demonstrated His unique deity. It is no wonder that very soon “the number of the disciples multiplied in Jerusalem greatly” (Acts 6:7).
