Annihilationism like Universalism is against the forum rules on many Christian forums, and the reasons are:
Annihilationism over the eternal punishment of the wicked is refuted biblically by examining the word 'aion' and 'aionos' which are the Greek words used throughout the N.T. to describe the eternal state of the wicked. Often proponents of the Annihilationism view will attempt to present the notion that 'aion' and 'aionos' do not really mean forever and ever, and do not mean eternal at all, but rather only a limited amount of time. Therefore the wicked aren't actually eternally in existence forever and ever, but only tormented and punished a limited finite amount of time.
However, this is a great flaw in the Annihilationism viewpoint. The reason is because if this premise were actually true; then the same level of consistency must also be applied when the terms 'aion' and 'aionos' are applied to the redeemed. In just as many places throughout scripture where we see the wicked eternally 'aion/aionos' suffering torment, we also see the redeemed eternally 'aion/aionos' reigning in Heaven with Christ. If 'aion/aionos' only means a finite, limited amount of time as Annhiliationism misinterprets, then for the redeemed Heaven will also be a limited stay; and nothing is eternal. The same scriptures that qualify God Himself as being eternal and forever and ever ('aion/aionos') must also be relegated to a limited time duration.
