2:42-47 In these verses we have the history of the truly primitive church, of the first days of it; its state of infancy indeed, but, like that, the state of its greatest innocence. They kept close to holy ordinances, and abounded in piety and devotion; for Christianity, when admitted in the power of it, will dispose the soul to communion with God in all those ways wherein he has appointed us to meet him, and has promised to meet us. The greatness of the event raised them above the world, and the Holy Ghost filled them with such love, as made every one to be to another as to himself, and so made all things common, not by destroying property, but doing away selfishness, and causing charity. And God who moved them to it, knew that they were quickly to be driven from their possessions in Judea. The Lord, from day to day, inclined the hearts of more to embrace the gospel; not merely professors, but such as were actually brought into a state of acceptance with God, being made partakers of regenerating grace. Those whom God has designed for eternal salvation, shall be effectually brought to Christ, till the earth is filled with the knowledge of his glory.

prayers—probably, stated seasons of it.
