Nope. God does not inject sin into people causing them to sin. He leaves them alone, knowing how they will sin. That does not make God the author of it. On the timing, what I'm saying is that it is unreasonable to say that man is running the show down here, and God just picks His openings for what He wants to happen based on the random chance of human acts. Instead of that I say God determined everything that is going to happen while outside of time. God is in control, not man.
What makes you say that man didn't have the wisdom to combat the serpent? They understood God's command to them - Eve wasn't confused. The problem was they fell to temptation.
They fell into temptation, but didn't have the wisdom to handle it, or even know what temptation was. What did they have of the knowledge of good and evil? Nothing, as yet. One needs wisdom to negotiate such issues, and God didn't give it to them, thus ensuring the result. They had no chance against the serpent. The fix was in.
And what about all the times where judgment is seen as a decision between heaven and hell?
What about them? I recognize there are those verses. We will go through a formal judgment for salvation. Believers will be found not guilty because the penalty has already been paid by Christ.
How is the judgement of your belief measured?
I.e., how is belief measured?
