Faith requires doubt.
I think understanding the nature of existence and consciousness are eternally beyond human capability. Christianity provides an attractive guide to living this life.
I think it is far easier to wrap your arms around Christian theology than grasp the complexities of quantum mechanics, which itself is unfathomable. In most cases I see no harm in Christian theology.
It seems there must be a continuous, eternal consciousness, we have consciousness, hence it might be said we are made in the image of God. I think Christians are really saying the same thing. I am not sure of the nature of our individual consciousness before or after this lifetime, but I think somehow we are part of it.
Rather than replace faith and doubt, I guess would just add reason and make it the big four. I find I usually really like Christians and the last thing I want to do is fan the flames of doubt about their theology, especially since I have no better explanation for our existence.
