Theists: what does your god want for you?

[Neo-Scholastic]

So then God's abilities are inherently limited? God cannot act in a manner contrary to his nature? Correct?

I know of no theology that allows God to act contrary to His nature. You are expanding the definition of limited beyond rational limits. That would make God absurd. For example, God cannot make Himself cease to exist. However, He can impose limits on Himself. That is called kenosis, the idea that God creates by withdrawing Himself from certain fields of activity.
