In these verses Peter gives one of the greatest sermons in all of the New Testament. He begins by stating that the Gospel rests in history. The long-awaited Messiah has already come. God made this promise to Abraham, Moses affirmed it, Samuel the first prophet and every prophet following made the same declaration. Just as Peter spoke to those who were present that day, his words continue to speak to us today. Open your ears and eyes, the Messiah has come, to be your Savior.
