Therefore, we must attend all the more to what we have heard, so that we may not be carried away.  For if the word announced through angels (the Mosaic Law) proved firm, and every transgression and disobedience received its just recompense, how shall we escape if we ignore so great a salvation (won by Jesus)?  Announced originally through the Lord, it was confirmed for us by those who had heard.  God added his testimony by signs, wonders, various acts of power, and distribution of the gifts of the Holy Spirit according to his will.

Hebrews 2:1-4
