I use the King James version of this Scripture today… because it states that it was the Church that God was adding to daily…(other versions say – God added to their numbers).    So what was so different about this particular group of people?  What we saw was unity and mutual care for one another.  There was fellowship, prayer, and the breaking of bread among them…but there was also evangelism outside the four walls.  The early Church was a delicate balance of both inward and outward focus…and God added to their numbers daily.
