John Wesley on Acts 3:19

Be converted - Be turned from sin and Satan unto God. See Ac 26:20. But this term, so common in modern writings, very rarely occurs in Scripture: perhaps not once in the sense we now use it, for an entire change from vice to holiness. That the times of refreshing - Wherein God largely bestows his refreshing grace, may come - To you also. To others they will assuredly come, whether ye repent or no.
