Thanks for sharing that. I would agree that these are various understandings from a variety of denominations on how someone might become a Christian, as you said "how it happens", but I'm really hoping to unlock what you a believe a Christian is. I'm sure we could wrestle back and forth between behavior and belief, on what makes someone a Christian, but how does God define one? What makes them different from non-Christians from His perspective? Are they someone who has had a change of mind, a change of behavior, or do they also have a change of nature? And, if a change of nature, what change(s) took place.
A change of nature, as well as of mind and behavior. But that doesn't make them error-proof or sin proof, unless you're a Christian who also believes a Christian can't really sin.
Now a question for you. If Lucifer can fall from heaven, where there is only perfection, what's to keep a Christian with even a changed nature from committing the very worst of crimes?
