You are not a ‘rotten sinner’. Neither is anyone else (with a few exceptions).
You Christians are your own worse enemy. No one created by God is a rotten sinner deserving of burning in an eternal hellfire. That is an affront to God, who created us to be His partners in Tikkun Olam, or ‘repairing the world’.
Yes, we can overcome sin and not be slaves to it.
Why is your religion so fear-based?
It becomes easier to see the former rottenness once a Christian has actually gotten a life well absorbed into the Lord (as opposed to being a biblicist in his own power). There is a strong mystical and spiritual side to this.
Suddenly, love and grace and caring spring forth that was, in fact, the norm that God had wanted from the beginning. Man went more or less AWOL. Even the Hebrew scriptures say so.
Yes it IS possible to over-concentrate on hell. A constant scare game is not the name of the game in Christian faith. Not even the Christian bible reads that way.
Another way to look at hell is that it is where the refuseniks go. Perpetually disdaining God and not wanting to have their lives absorbed in His (and paradoxically then imbued with a new distinctiveness, not a monotonous sameness) they go to a place that God will accommodate their hate. If you refuse to be forgiven, then you won’t be forgiven. People’s choice, not God’s.
What you call tikkun olam is a witness of God’s saving power, but can’t ever be complete in this mortal coil and God doesn’t expect it to be complete. A new, totally re-created world is coming. We have to die in the old one before being fit for the new one.
