Lest We Drift Away

Hebrews 2:1 Therefore we must give the more earnest heed to the things we have heard, lest we drift away.
2 For if the word spoken through angels proved steadfast, and every transgression and disobedience received a just reward,
3 how shall we escape if we neglect so great a salvation, which at the first began to be spoken by the Lord, and was confirmed to us by those who heard Him,
4 God also bearing witness both with signs and wonders, with various miracles, and gifts of the Holy Spirit, according to His own will?
