Im sure this guy doesn't mean it this way but:
Doesn't this line of thinking ultimately mean that eternal life with Christ, co-ruling in the New Heavens and New Earth, enjoying *shalom* and God's intention for humanity, is just not that appealing?
The problem with annihilationism is it destroys any need for the Gospel. Most people will choose to cease to exist than a life of suffering for Christ. There is no longer an incentive if everyone will no longer exist. Its easier to live in sin and then die awaiting a time you are destroyed forever as if you never existed. The urgency and need for a savior is taken away. Its why this teaching comes from Satan.
