In Hebrews 10:26-31, the author, after encouraging the people to hold fast to their confession, offers a warning to all of those who turn away from Christ. Ultimately, the sin of apostasy is worse than any other. Not only that, but apostasy under the New Covenant is much worse than that under the Old. Here is the warning: do not turn away from Christ. It is a fearful thing to fall into the hands of the living God.
