acts 12:15 And they said unto her, Thou art mad. But she constantly affirmed that it was even so. Then said they, It is his angel. - Free Bible Online

      15. Thou art mad--one of those exclamations which one can hardly resist on hearing what seems far "too good to be true."
      she constantly affirmed--"kept steadfastly affirming."
      that it was even so. Then said they, It is his angel--his disembodied spirit, his ghost; anything, in fact, rather than himself. Though this had been the burden of their fervent prayers during all the days of unleavened bread, they dispute themselves out of it as a thing incredible. Still, it is but the unbelief of the disciples who "believed not for joy and wondered" at the tidings of their Lord's resurrection. How often do we pray for what we can hardly credit the bestowment of, when it comes in answer to our prayers! This, however, argues not so much hard unbelief as that kind of it incident to the best in this land of shadows, which perceives not so clearly as it might how very near heaven and earth, the Lord and His praying people, are to each other.
