“And I say to you, My friends, do not be afraid of those who kill the body, and after that have no more that they can do.
But I will show you whom you should fear: Fear Him who, after He has killed, has power to cast into hell; yes, I say to you, fear Him!" Luke 12:4-5
"God's revelation is in the Bible. We get our knowledge of heaven from the Bible, we know nothing of heaven apart from it, but it speaks of hell as well as heaven. If we accept the one we cannot consistently reject the other. Take the words of the Lord Jesus Christ. He said, "In my Father's house are many mansions: if it were not so I would have told you" (John 14:2). If there had been no place and state of blessing beyond this life for us, He would have told us plainly; and if there had been no judgment to come, no retribution for sin, no hell, would He not also have told us? But the strongest language in the Bible as to these things came from His own lips. He spoke of some who would die in their sins and the impossibility of such going where He would be (John 8:21, 23, 24). He said to the proud self righteous hypocrites of His day, "How shall ye escape the damnation of hell?" (Matt. 23:14). He said, "Fear Him which, after He has killed has power to cast into hell; yea, I say to you, Fear Him" (Luke 12:5). He it is who will say to some in the day of judgment of the living nations, "Depart, ye cursed, into everlasting fire, prepared for the devil and his angels" (Matt. 25:41), and of these He said, "these shall go into everlasting punishment" (Matt. 25:46). He spoke of "outer darkness" and "weeping and gnashing of teeth" (Matt. 25:30), and "of their worm that never dies and the fire that is not quenched" (Mark 9:46). Who dares to say that he will listen to the Lord and believe Him when He speaks of blessing, but refuse to hear and believe when He speaks of judgment?"

"Salvation never has been, is not today, and never will be by reformation. Salvation is by faith and on the ground of the penalty and retribution of sin having been borne— of old typically in connection with the sacrifices, now borne really and fully by the sacrifice of Christ Himself upon the cross...
Some people think that eternal punishment cannot be reconciled with the fact that God is love, and therefore they refuse to believe it. Is there any force in this argument?
None whatever. The Scriptures reveal equally both facts, so that those who speak thus are really leveling their accusation of inconsistency at the Bible.
As a matter of fact, however, there is no inconsistency at all, but the very reverse. The strongest possible abhorrence is quite consistent with the strongest possible affection; we would indeed go further and say it is inseparable from it. It is impossible to regard any one with deep love and not heartily hate all that imperils that person in any way.
There is nothing, therefore, incompatible with God’s love in His declared purpose to segregate all that is evil in eternity. At present good and evil seem hopelessly mixed in this world. A day is coming in which they will be finally disentangled. Good will bask in the sunshine of His favor. Evil will lie eternally beneath His frown. Thus, evil, eternally shut up in its own place, and enduring its just penalty, will no longer be able to threaten the peace and blessing of God’s redeemed creation.
No one regards the isolation of smallpox patients or the still more sorrowful life-isolation of lepers as measures incompatible with benevolence amongst men. Why, then, object to God acting with similar intent in eternity?
