You said: Not everyone enters eternal life (AIONIOS ZOE), few will find it.
Many will enter eternal corrective punishment (AIONIOS KOLASIS), they will go through a destruction of the sinful nature.
All will enter into the Kingdom, only few will reign in this Kingdom. There are the rulers of the Kingdom (those in AIONIOS ZOE) and then there are the subjects of the Kingdom (those in AIONIOS KOLASIS).
Aaron: Ok. When Jesus says " Few" will find eternal life, that includes ( corrective punishment, or whatever other way you use for unbelievers to find eternal life). Either you are in error or Jesus does not know what “few” means. Jesus says “Few” find eternal life. Jesus does not say “All” will find eternal life. You can use whatever word you want to describe eternal life, but Jesus is very clear on how many will actually believe and find eternal life… “FEW”
