IROC, I was raised in a presbyterian household although looking back I was just going through the motions because my parents wanted me to.

Going to church was a chore, like mowing the yard.
By the time I reached my twenties and was out on my own, I had come to the belief that there was no God. It was the worst, most unsettling period of my life. Up to that point I concidered myself a rational, scientific person, although unhappy and unsatisfied. All the riches in the world are not enough, we always want more. Just a little more. It never ends. There just had to be something better out there.

Many years later I went to church to keep a girlfriend happy. Again I was going through the motions. I was bored so i picked up a pew bible and started reading. Then I went out and bought a bible.
I was still skeptical but was interested so I kept reading.
It didn't take long for things to make sense, not only the things I read but the things I had experienced in my life. I really was that obvious. All I had to do was open my eyes, up to that point I was constantly looking away from God, doing everything I could to explain why there couldn't be a God. I worked very hard to not allow myself to believe. I didn't really go looking for God, I just dstopped fighting it and allowed him to come to me. He gave us that choice.

Yes, I am absolutely certain that there is a God and that he loves me and has forgiven me for being imperfect. He is and was always there, and came to me when I needed him most.

Yes I rejected god but he never rejected me. It was not too late and never is as long as you have the breath to call to him.

Saying that when some people reject Christianity it means it is false is absurd.
A person with true faith does not completely leave God or reject his teachings. We all are tempted and Satan may try to test our faith, but true belief is so powerful that not even Satan can destroy it.

A better explaination for your scenarion would be that a person who does not have faith (or who has not yet obtained a true faith) may decide to stop pretending. Even that is not necesarily permanent as was my case.
