In your number two question, I know that you probably will not agree with me. However, I have attended a non-Reformed Church before that for the most part other than the doctrines of grace issue, I felt at home. I stayed there mainly because at the time, I believed it would open a huge can of worms with my family if I left.
I knew that if I left my wife and two daughters who were very much a part of that body, would not leave with me. However, I also was growing in other area there and I thought until God gave us a more Biblical Church, I would stay there unless the Church started to become liberal.

Believe me, I wrestled in prayer, consulted with other Reformed Christians and in the end, what I said above is what I ended up doing. I knew that not everybody would agree with my decision, but I definitely didn't make that decision lightly.
Hope that answers your question.
