The Immorality of Unbelief

“But the...unbelieving, and…whoremongers...shall have their part in the lake which burneth with fire and brimstone.” Unbelief is a terrible thing. It’s kin to the abominable, murderers, whoremongers, sorcerers, idolaters and liars. Unbelief is immoral. It’s the most serious of all sins. It’s the only thing that damns the soul (Mk. 16:16b).

Christians seem to think that their initial faith in Christ was sufficient for all of life, not realizing that was only the beginning. Our life is to be “from faith to faith.” From start to finish, it’s faith. Paul said, “The life I now live I live by the faith of the Son of God.” He said in another place, “The just shall live by faith.” Dear friend, do we not realize “without faith it is impossible to please God”? 

 We do not consider our sins to be as vile as the ones mentioned in our text. But unbelief is as immoral as whoremongering. In the Old Testament, when the people of God ceased to put their faith in the Lord, and turned their backs on Him, the term the Bible uses is “Then were they defiled...and went a whoring.”

“Take heed, brethren, lest their be in any of you an evil heart of unbelief, in departing from the living God.” (Heb.3:12).
