Winston, you may have already read through all the passages sighted in this post, but maybe not, so I am sending a ping.
R.A. Torrey authored many books and the one I treasure is "The Power of Prayer". Does prayer change God's mind or does prayer change ours?
A very apt question. What is your answer?
Mine is "Both, at different times." I think we would all agree that, through prayer, God can change our minds. But Scripture clearly and unequivocally tells us that prayer also changes God's mind. No problem with that, right? :-) Or, is He also to be numbered among the immobile "frozen chosen"?
