Some thoughts: Established world religions have served the internal, psychological/spiritual needs of humankind( recall we're told all persons are created in an image of God) from the historical rise of human consciousness out of unconsciousness.
At the heart of these legitimate symbolic religions, including the original Christ religions, is the psychological/spiritual truth, " The Kingdom of God is in you." That is that 'God things' are primarily descriptions of spiritual, not material reality.
An unfortunate thing is in the past 400 years the Christ religion has been interpreted literally, that is materialistically, not as first an internal spiritual reality. This has happened primarily in an effort to make the ancient religious statements of our culture logically compatible with the ever-growing materialistically true statements of science.
This misguided effort to make important religious statements such as the 'virgin birth of God' , 'baptism into Christ', "walking on water", a one-time physical 'second coming of Christ' and so many more be material/literal statements effectively closes the door of the human logical mind. This prevents these spiritual realities from being received as spiritual/psychological knowledge of the heart. The statements then lose their transforming power for human heart/soul development. And we wonder 'Why is religion not fulfilling its purpose to make life more compassionate and peaceful on earth?'
Christians now find themselves forced to be 'believers' in what they conscientiously 'know' are materially nonsense statements and doctrines. This results in a breaking of true conscience (of the human experience of being honest with onesself) rather than having a natural genuine trust from internally directed spiritual statements; statements and symbols which naturally fit human inner needs effectively and potentially personality transforming.
This kind of psychological explanation imo is a spiritual internal path and process by which one may actually become spiritually 'religious' and experience such 'real' inner undeniable effects as 'amazing grace', 'eternal salvation', 'joy unspeakable', 'trust in life', 'peace that passes understanding', patience, love, eternal hope etc. etc.
