Hebrews 2:1-4, How shall we escape, if we neglect so great salvation

Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip.

2 For if the word spoken by angels was stedfast, and every transgression and disobedience received a just recompence of reward;

3 How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him;

4 God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will?
