God gives us the grace we need to reform from bad habits.
But He does not take away our free will and drive us like robots.
If we consciously give up our free will, quit trying to force our will and our way on life and ask God to lead us with His grace....He does.
The 12 steps are a simple and practical process of repentance mostly derived from the book of James. ‘Let go and let God’ refers to our will (ego) - which if you have completed step work you will seek His will always. ‘Self will run riot’ is used in the 12 step literature as what we are trying to avoid.
