[You are the one claiming that Christ never existed. To claim that you had a personal relationship with one who you now claim never existed is a contradiction in your logic. To make your statement true, the relationship had to be imaginary, either that or your current state. Make up your mind and go for it.
The experience and the relationship was real, but it was directed at an imaginary figure. It was childlike, in the same way that small children have relationships with imaginary friends. Are those relationships unreal because the friend exists only in the child's mind? Who are you to say what experiences are real?
I have similar experiences these days without the focus on Christ.
You are of course missing the point. You may have real feelings with your imaginary friends. Of course that is your business and of no interest to me. My interest is your obsession with proving that God does not exist. I have no problem with you not believing in God, that is your issue. Trashing Religion, goes beyond yourself and effects others.
I could take another tack and ask why you post here, not believing in God, you spend allot of your time on something someone who claimed to be Agnostic or Atheist, you claim to want nothing to do with. At least that is the appearance. We Each have Life experiences, lessons learned along the way, that teach us. Why deny the source? Why the adamant behavior towards those that truly believe? I'm not adamant towards you for not believing. Why isn't it enough for you, yourself to not believe?
