Doubtless our minds have difficulty wrapping themselves around creation ex nihilo but not progressive evolutionism because evolutionism speaks of one thing happening after another thing and this process describes how our minds work.
We think as we speak. First one word, then another and another, each word following after the one before it and never more than one word at a time. Thus our need for faith for what our minds cannot grasp.
Thank you for sharing your insights, dear spirited irish!
