Most glossaries are alphabetical, but we don't live alphabetically. We don't Run before we Walk, or get Healed before we Suffer. But go ahead and use the alphabetical index to skip to a topic (you think) suits your current stage of progress. A good definition is like a custom-made box, uniquely sized and shaped so all the essential parts fit, without leaving extra room for a word to carelessly slosh around with other words that have similar but not identical meaning.
I wrote this book! It's the book I wished I'd had when I first became a Christian. I didn't grow up in church, and I didn't know where to go with my questions. This is an orderly presentation of my personal notes from my personal studies and my personal relationship with God. I hope it blesses you.
