Acts 4:32

We have a general idea given us in these verses, and it is a very beautiful one, of the spirit and state of this truly primitive church; it is conspectus saeculi - a view of that age of infancy and innocence. I. The disciples loved one another dearly. Behold, how good and how pleasant it was to see how the multitude of those that believed were of one heart, and of one soul (Act 4:32), and there was no such thing as discord nor division among them. Observe here, 1. There were multitudes that believed; even in Jerusalem, where the malignant influence of the chief priests was most strong, there were three thousand converted on one day, and five thousand on another, and, besides these, there were added to the church daily; and no doubt they were all baptized, and made profession of the faith; for the same Spirit that endued the apostles with courage to preach the faith of Christ endued them with courage to confess it. Note, The increase of the church is the glory of it, and the multitude of those that believe, more than their quality. Now the church shines, and her light is come, when souls thus fly like a cloud into her bosom, and like doves to their windows, Isa 60:1, Isa 60:8. 2. They were all of one heart, and of one soul.
