So Great Salvation

Hebrews 2:1 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?
