Hebrews 2:1-4 English Standard Version (ESV)
Warning Against Neglecting Salvation
2 Therefore we must pay much closer attention to what we have heard, lest we drift away from it. 2 For since the message declared by angels proved to be reliable, and every transgression or disobedience received a just retribution, 3 how shall we escape if we neglect such a great salvation? It was declared at first by the Lord, and it was attested to us by those who heard, 4 while God also bore witness by signs and wonders and various miracles and by gifts of the Holy Spirit distributed according to his will.
Hebrews 2:1-4 New International Version (NIV)
Warning to Pay Attention
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.
