Here's an excerpt from a post I found over at "Possessing the Treasure". Thanks Mike.
"To be separated from God is to be separated from anything and everything good. That is hard to conceive because even the most miserable person enjoys some of God’s blessings. We breathe His air, are nourished by food that He supplies, and experience many other aspects of His common grace.
On earth even atheists enjoy the benefits of God’s goodness. But in hell, these blessings will be nonexistent. Those consigned there will remember God’s goodness, and will even have some awareness of the unending pleasures of heaven, but they will have no access to them.
This does not mean that God will be completely absent fro hell. He is and will remain omnipresent (Ps. 139:7-8). To be separated from the Lord and cast into hell does not mean that a person will finally be free of God. That person will be forever separated from God in His kindness, mercy, grace, and goodness. He will be consigned to deal with Him in His holy wrath.
Secondly, hell is a state of association. Jesus says that the eternal fire of hell was “prepared for the devil and his angels” (Matt. 25:41). People were made for God. Hell was made for the Devil. Yet people who die in their sin, without Jesus Christ as Lord and Savior, will spend eternity in hell with the one being who is most unlike God. It is a tragic irony that many who do not believe in the Devil in this life will wind up spending eternity being tormented with him in hell.
The third truth is that it is a state of punishment. Jesus describes it as “fire” (v. 41) and a place of “punishment” (v. 46). Hell is a place of retribution where justice is served through the payment for crimes.
The punishment must fit the crime. The misery and torment of hell point to the wickedness and seriousness of sin. Those who protest the biblical doctrine of hell as being excessive betray their inadequate comprehension of sinfulness of sin. For sinners to be consigned to anything less than the horrors of eternal punishment would be a miscarriage of justice.
And that brings us to the fourth truth - hell is an everlasting state. Though some would like to shorten the duration of this state, Jesus’ words are very clear. He uses the same adjective to describe both punishment and life in verse 46. If hell is not eternal, neither is the new heaven and earth.
How can God exact infinite punishment for a finite sin? First, because the person against whom all sin is committed is infinite. Crimes against the infinitely holy, infinitely kind, infinitely good, and infinitely supreme Ruler of the world deserve unending punishment. In addition to that, those condemned to hell will go on sinning for eternity. There is no repentance in hell. So the punishment will continue as long as the sinning does."
