Pentecost gave hope

Pentecost was more than God’s certification of the Church as His house of worship. It was first and foremost, His certification of the Messiahship and Divine Sonship of the One Whom the Jews had crucified. It was proof that Christianity was not just another "religion." Without this fact, Christianity would never have been heard of beyond the walls of Jerusalem, for it would have had no hope, no power, no message.
