" Although I don't particularly like all the ideas of the God of the OT, I find the concept of Christ appealing, but I lack faith and am unsure if I want to regain faith or pursue an atheist/anti-theist course."
This was troubling to me as well. I also realized a few days into my re-re-re-re-re-reading of the Gospel that I was doing something wrong. I kept trying to seperate the OT from the NT. They are not to be seperated as they are one book and Jesus himself said something to the effect that he who has seen me has seen the father. Jesus quoted from the OT so no doubt he was in harmoney with it. That was a little difficult to grasp. So I prayed and prayed for understanding as the bible directs.
I hope you do the same. Read the bible as a whole realizing that there is no seperation in scripture besides that which man has made (OT vs NT).
Re-read the bible/ pray for an answer to your questions as the bible instructs, then make your decisions accordingly
