The Acts 2:41-44, 47

They then that received his word were baptized: and there were added unto them in that day about three thousand souls. And they continued stedfastly in the apostles' teaching and fellowship, in the breaking of bread and the prayers. And fear came upon every soul: and many wonders and signs were done by the apostles. And all that believed were together, and had all things common

praising God, and having favour with all the people. And the Lord added to them day by day those that were being saved.
