Pisteuo is 4100 in the Strongs. I've been studying every aspect of pisteuo for over 30 years. The fact your just googling it doesn't get me very excited. I thought you were going to point out the " sink holes " in my understanding? You got my hopes up that I might get to know Him better!
I am now in my Strong's looking at 4100 -- is says :from 4102 -- to have faith, etc. the same thing that I found in Google. Truthfulness of God - reliance upon God or a relig. teacher) espec. reliance upon Christ for salvation. --- assurance, belief, believe, faith, fidelity.
Honestly -- since I've already shared my thoughts of your 5 stages and don't think you agree with me in my thoughts.
I, also suspect that you're okay with getting to know God , Jesus Christ but on Your terms because you are persuaded that the English translation is faulty.
And you've shared that you've been studying every aspect of pisteuo for over 30 years. Do you really believe there Are 'sink holes' in your understanding?
It would probably require a theologeon to sit down with you and share. That person would need to know the ins and outs of Greek and English.
