Again, the way I view what a spiritual paradigm shift is that of a major doctrinal change or one on theology.
The paradifm shift I had on learning about body, soul, and spirit caused me to view myself totally different. before I had a very bad habit of looking down on myself, feeling guilty, defeated, etc., etc. When I learned that God wasn't mad at me because in spirit am I am the righteousness of God in Christ, but only in my spirit, I did rejoice! I then learned that by putting off the old self and putting on the new self didn't sound so difficult to do where as before I felt it impossible.
I thought, this new self, what is it and how do I know I have it. I really didn't believe I had this new self. But all of us born again christians do have it, it's the righteous and holy born again spirit that God created in us when we first became born again. Anyway, once I found this out I no longer hate myself or feel guilty and can trust in God to do all the changes in me that are necessary.
As for the negative spiritual paradigm shift, it's a long story but suffice it to say, I grew to hate myself out of feeling guilty because I could not control my old self from taking over. I was like Paul in the 7th chapter of Romans. I then grew to blame God for it all and became very disillisioned. For a long time I didn't want to have anything to do with God. I was like one of those who would only pray when I got in real trouble, otherwise I never prayed to him yet still believed in him.
All of this took a long period of time though. None of what I said, baring my first born again experience, happend in one day. Actually my born again experience grew on me too. In the RCC at age 14 I was studying to be confirmed and was reading the Bible every night. And wha-la, the Holy Spirit grabed me, but I didn't make a decision on it until after a few days, or weeks, can't rightly remember.
