Hi Scott
.
I wanted to clarify your question: does God control our mistakes in the sense of "making us" decide what we do? No, the Bible says God does not tempt anyone to sin. (James 1:13--"Let no man say when he is tempted, 'I am being tempted by God', for God cannot be tempted by evil, nor does He tempt any man.'") Does God test our hearts and use our decisions and their outcomes toward His own purpose? Absolutely.
Laban repeatedly made the choice to try to cheat Jacob out of his wages ("Here, you can have all the speckled, spotted, and blemished lambs.") It looked like a sure disaster for Jacob, but God had other plans. His will was to bless Jacob, so even though Laban made the conscious decision to repeatedly lie and cheat, guess what happened? Laban's flocks began to produce uncanny numbers of speckled, spotted, and blemished lambs, and Jacob became extremely wealthy. Laban made the choice--God neither coerced nor forced him to act dishonorably, but God did control the outcome.
In one of my college classes, we were assigned a lab rat and an experimental (Skinner) box. Our objective was to shape various behaviors the rats would make (they were water-deprived for 24 hours and we could reinforce, or reward, their behaviors with a dipper that gave the rat a drink of water.)
During my sessions with my rat, I noticed that for whatever reason, he would often turn in a circle. I have no idea why--he just did so "naturally"--and through many sessions, I was able to shape up that behavior by giving him water every time he turned in a circle.
For our final project, we had to demonstrate that we could "get" our rats to do a series about 5 behaviors before they would get a drink of water. There was a list of both required behaviors that we "had" to show in our experiment, but there was also the option of including behaviors that weren't on that list.
This was many years ago so I can't remember everything I was able to "train" my rat to do, but when it was my turn to show my project, my rat would do something like this: touch a certain marked spot inside the box, pull a chain, turn in a circle, wait for a light to come on, press a lever, and then receive a drink of water. All the other behaviors were "required" according to the list, but turning in a circle was not, and everyone asked me how I had gotten him to turn in circles.
The truth is, I have no idea why he originally turned in circles. Did I control his behavior or choice to turn in a circle? No. But did I take that behavior and use it for the purpose of enhancing my final project? Absolutely.
I know this example can't be compared to an Almighty God, but I believe that God knows what choices we will make long before we ever make them, and because He knows that, He is absolutely able to use what He already knows about our decisions for His own purposes. (Romans 8:28--"We know that in all things God works for the good of those who love Him, who have been called according to His purpose.")
