Hebrews 2:1-4 NIV
We must pay the most careful attention, therefore, to what we have heard, so that we do not drift away. For since the message spoken through angels was binding, and every violation and disobedience received its just punishment, how shall we escape if we ignore so great a salvation? This salvation, which was first announced by the Lord, was confirmed to us by those who heard him. God also testified to it by signs, wonders and various miracles, and by gifts of the Holy Spirit distributed according to his will.
