Belouie,
Thank you for sharing your personal experience and resulting beliefs. While I agree with some of your argument, specifically that heaven was created by God (premise 1) and that heaven is the antithesis of hell (premise 3), I would like to challenge your second premise and resulting conclusion. Please note that for this argument I am writing from an explicitly Christian view point, thus excluding the other aforementioned Abrahamic faiths.
"2) If heaven was created by God, who is love, then heaven is for people who inspired, cultivated and perpetuated love while on Earth."
"4) Therefore, hell is a place for people who inspired, cultivated and perpetuated hate while on Earth."
I believe that these premises do not entirely capture the importance of Jesus' great act of salvation on the cross and the resulting grace offered to those who believe. Although your argument sounds like a wonderful system of universal discipline at first glance, upon further review I find it hard for me to determine where I would reside after my time on earth ends.
Unfortunately, I often cultivate hate of some form, be it my personal disdain for a certain politician, my implicit hate for the earth through my blatant disregard of my gasoline usage, or simply the absence of love for a neighbor in need. Sure, I often love others as well (and certainly strive to do so regularly), but on any given day the balance between love and hate may ultimately lean toward my place in hell as described in your argument. (Although, to be fair, I recognize you did not attempt to delineate the exact tipping point between cultivating hate and cultivating love.)
Thankfully, I recognize the grace offered through the death and resurrection of Jesus on the cross. As He took the punishment for my sins (or, in other words, my habitual hate), I do not have to worry that when I sin/perpetuate hate I will be forever separated from God in heaven. Instead, I can rest assured that I will be with God due to the fact that I have chosen to accept God's gift of love by my belief in Jesus and acceptance of the grace given to me as a result of His resurrection. I know that the only way I will be separate from God in the afterlife, is if I choose to deny God's gift of love through blatant disbelief.
There's obviously much more to the concepts of grace and salvation, but in an effort to be concise, I offer my version of your argument as follows:
1) Heaven was created by God, who is love (1 John 4:8 ).
2) If heaven was created by God, who is love, then heaven is for people who accept God's gift of love by believing and accepting the salvation and grace offered by Jesus.
3) Heaven is the antithesis of hell.
4) Therefore, hell is for people who deny God's gift of love by not believing and not accepting the salvation and grace offered by Jesus.
I welcome your questions and comments. Thanks for reading.
