For this reason we must pay much closer attention to what we have heard, lest we drift away. For if the word spoken through angels proved unalterable, and every trespass and disobedience received a just penalty, how will we escape if we neglect so great a salvation? That salvation, first spoken by the Lord, was confirmed to us by those who heard, God also testifying with them, both by signs and wonders and by various miracles and by gifts of the Holy Spirit according to His own will.
