Series Sermon #16: The author of Hebrews has been pushing his readers not to be sluggish listeners of God's Word. He is not content with believers who won't press forward to learn more about Word of Righteousness. In this passage, he gives further instructions about how those who have gone astray should respond. It is impossible for them to go back to repentance. Instead, they should go on to deeper knowledge and obedience to the Word.
