I did a message on this a while ago called A Good Defense.
This article along with another I posted explains “unanswered” prayer very well.
I don’t believe in “unanswered” prayer per se, I see them as prayers where I didn’t get the answers I wanted or expected. I have an answer, in my self-delusion, I think God failed to answer or wasn’t listening… that is not true. I just didn’t get what I wanted, tantrum, because it wasn’t what he knows I NEED!
His will, not mine be done! It is only when my life and will are aligned with his that he promises I will have everything I ask for, because I ask according to HIS will. See 1 John 5:14…
