Hebrews 2:1-4

1We must pay closer attention, therefore, to what we have heard, so that we do not drift away. 2For if the message spoken by angels was binding, and every transgression and disobedience received its just punishment, 3how shall we escape if we neglect such a great salvation?

This salvation was first announced by the Lord, was confirmed to us by those who heard Him, 4and was affirmed by God through signs, wonders, various miracles, and gifts of the Holy Spirit distributed according to His will.
