I really like how you are approaching things in your christianity, Squeek.
I myself, back in 1990 when I became a christain, actually, it was really 1992, but I began my studies back in 1990. For about two years, until I accepted the Lord in 1992, I tested all the faiths to the best I could, to find who seemed to really have the Spirit leading the faith. I believed that, as scripture says, 'if you seek, you will find.' It took me to years, but thanks be to God, he led me to what I personally still believe to this day.
My big obstacle that I went through was between 'born again christianity' and the Jehovah's Witness's.' I had friends that I was able to meet of both faiths. I had many things taught/shown to me. It was tough. They both had strong arguments. Kessel offers strong arguments too, he is well versed in the scriptures, as the JW's often are. But, through a bit of time, I found the errors of their ways both through the Watchtower and their scripture understandings that so often would make God out to be a liar. Plus, there position on Israel, that Israel's covenants were no longer in effect was wrong. These covenants were everlasting, unconditional, so they must still be today.
