Hell is not eternal

Matthew 25: 41: Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:

Hell is a dimension created for Satan and his devils, therefore it had a beginning and will have an ending when it is cast into the Lake of Fire (Revelation 20: 14). It is a world that God created and then withdrew His attributes from, so nothing about that place has any resemblance to Him. Because it is not an eternal world, then those who reside in it cannot have eternal life. If eternal life existed in Hell, then Jesus died on the cross in vain, because all who believe on Christ receive eternal life according to John 3: 16: For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. Hell is a temporal world, and all who are in Hell have only a temporal existence, for they too will be cast into the Lake of Fire, and their souls will later be extinguished into non-existence.
