Universalism makes a lot of sense so thanks
@Cormack for raising the topic.
A definition of grace I like is that there nothing we can do to make God loves us more, and nothing we can do to make God love us less. A few comments have said that universalism isn't biblical but I think the parables of grace like the Prodigal Son, the king who cancels the debt that the servant couldn't possibly pay off and the employer who pays the latecomers the same as the all-day crew do support the idea because they say that we don't have to do anything in order to be accepted by God - saved in other words.
I think the comments about Hitler are natural because we intuitively think that a price has to be paid for such crimes. But if the price has been paid by Jesus on the cross then this moral dilemma between justice and forgiveness has been solved once and for all.
The idea mentioned in this discussion that God would be forcing us to go to Heaven if we don't want to go this overriding our free will don't hold water. If we are created in His image then we are meant to want to be with Him however much we were corrupted like Hitler was while on earth.
I started off hoping that all will be saved but I'm beginning to think we all will be. The simplest argument for it is that it's what God would want because we are His beloved children and He will ultimately achieve His desire.
