On heaven and hell..
1. It is often thought Heaven is the end-goal. The vision of God in his essence. But in view of the redemption by Jesus Christ it is only resuming the start of Creation as intended by God. Had we not sinned then all of history upto and including our present times would not have been necessary. What we think of our earth, its history and our wish to let it stay as it is, whilst actually destroying its potential to start with men redeemed on its real course, means nothing. Real Creation still has to start. Which is why we can't see Heaven.
2. Co substantial with God the Father is his idea of men. When he thought of his creation of Adam (and Eve) He willed this from the start. Which is why 'in the beginning was the Word (logos) and the Word was God and was with God'. Which why Jesus is co-substantial with the Father and God cannot be otherwise.
Jesus is not the messenger, but the self revelation of God, into His creation. Which is why this reality exists with God outside time from the beginning and God needed to create man, in view of his own essence.
3. Immediately upon conception Gods creates for each human a soul. Ideally both the material/spiritual man and his soul grow together, but in reality that does rarely happen. A healthy soul in a healthy body. If we want to realise our true self, we need to seek the Kingdom of God first. Seek first the Kingdom of God and the rest will be added unto you. Babylon does not want to understand this. It wants it all in the flesh. When we accept the cross in our lives, we nourish the soul so both can grow up to maturity, till the flesh dies and we receive a new body. Then real creation starts. Real Self.
4. St. Paul did not mean that we have to 'add' to what Jesus Christ suffered on the cross. His death and redemption of man is enough for everybody. But we have to 'add' what is lacking in the suffering of Christ, in our own personal life, namely. the suffering caused by our own failings and mistakes. Only we can do this. Nobody can do this for us.
5. Therefore. We cannot redeem others and don't have to, only Christ can. There is no pool of sufferings, where we have to contribute to on a daily basis, and if we don't do that other people or the world will go to hell. If you carry your own cross in view of your own life, God will do the rest. Those who don't, let us hope they won't understand it until the last judgement. God's burden therefor is light. Don't let others bind more onto you than that...
6. I heard someone say. "Hell is necessary for the Elect to live in comfort". This is soooo wrong! It takes spiritual values as if there is only one limited source of it and you have to somehow take care that you get more of it than others, like for instance money. It turns Christians into Pharisees, with a very limited world view and view of other people. There is enough for everybody in the redemptive act of Jesus Christ.
