I have provided them already right at the begining of the thread, to give people a valid reason for understanding, and why people don't understand, the reason things change for people, is because people trust in his means he has already provided to change things for anyone person. Which means circumstances for any one person can only change on that bases and we can't change his mind ourselfs, but it's not him who's changing his mind it's the means already provided that has changed the person, as if the person didn't change nothing would change. This is the whole point to the sermon, that God is sovereign over all things, and knows all things and ordained the ends to all things but he also ordains all the means to the ends of things before hand, which means he's always had a perfect plan for the future which we can't change , which means we can actively take part in his sovereignty by trusting in his will.
