I don't believe in eternal damnation, just destruction in the Lake of Fire. Throw them in, they burn like paper and it's over. But let's go back to the beginning. God told Adam and Eve if they eat of the Tree of Knowledge of Good and Evil, they will surely die. They did, but did they immediately die? No. What happened, physically, death would come much later, but their cells began to die, they aged. But it was the spiritual death, which is the separation of God. We inherited that death. We are all born spiritual separated from God. The purpose of mankind is to reconcile with God through Jesus - sometime in their life. All those who physically die who have not reconciled with God, will go to Hades and await their final judgment - destruction. Now many would argue with me on this since eternal destruction has been a traditional belief. However, the word used for eternal or everlasting, aionios, has variable meanings. When it is applied to our temporal realm, that will pass away, it means ages, lifetimes, generations, epochs, age-lasting or age-during, but it is temporal. So if the Lake of Fire is part of the earth and possibly more of an event in or one earth, then it is temporal, since the earth will be destroyed someday and replaced by a New Earth (Rev. 21:4; 2 Pet. 3:10) When aionios is applied to God, His domain or our salvation, then it should be translated as eternal.
Jesus sacrifice was sufficient for the entire planet, but His offer for eternal life, a gift, the washing away of all your sins, requires the individual to believe in Him. Basically the gospel is summed up in one sentence: Jesus died for our sins and rose on the third day according to the scriptures. Throughout the NT, the concept of putting your faith in Jesus is compulsory. He doesn't force anyone, He draws all men to Himself, but some resist and reject His offer. So then His blood cannot be applied to them. It's perfectly fair!
To believe or not to believe, that is the question.
