Hebrews 2:1-4
2 We must pay the most careful attention, therefore, to what we have heard, so that we do not drift away. 2 For since the message spoken through angels was binding, and every violation and disobedience received its just punishment, 3 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. 4 God also testified to it by signs, wonders and various miracles, and by gifts of the Holy Spirit distributed according to his will.
