So you've put people into these neat little psychological boxes, "optimists", those who are "aware of their sinful state" but don't know their "true spiritual condition". You say that the optimists seek their "higher self", maybe this is true in some New Age things - I think the corruption of the whole New Age movement is pretty obvious - but it's far from universal. For me the "Higher Self" is a kind of satanic doctrine, divinisation of the ego. I also feel that we do need the Christ, the Inner Christ, in order to overcome ourselves. There is a kind of separation from God and there is a kind of Grace that we need, I just don't think that this means simply holding some belief, it takes spiritual work, struggle.
