The book of Hebrews, in all its depth and sublimity, is, in many ways, just one long exhortation to Jewish believers in Jesus. And what it exhorts them to do is: Stay faithful to the Lord! This faithfulness, of course, should stem from our love of God, of who He is and of His character and goodness, most powerfully expressed at the cross of Christ. Sometimes, though, human beings need to be reminded of what the terrible consequences of falling away will be.
