I completely a hundred percent believe God answers our prayers, even when time seems to say otherwise. Is your mother saved? You don't have to answer but consider it. Would she hurt you so if she had any insight. God gives us insight. Because of God, I am able to see the truth that my mother has always searched for love in all the wrong places and has never experienced real love which only God can give. My biological Father passed never conquering alcoholism or coming to terms with the truth that, he also was a bastard child. Those that don't know God seriously know no other way. My mother mocks my relationship with God, even when I tell her it was My Heavenly Father that decided when I could handle the truth coming out. That He did what was good for me when I needed it. I am able to take my mother's comments and bitterness because God has clearly shown me it all stems from the lack of Him.
So, don't assume an almighty God has lost control of how you are treated. Please don't assume He does not care. Don't assume He is not using how YOU honor Him by doing one of the most difficult things for you to do. Even if it makes no sense whatsoever, He IS God and sees and knows what you do to honor Him...even if it doesn't give you the results you want. I have had prayers that took ten years to be answered. God began working on those prayers when I asked them. And here's the kicker...I have only had a relationship, a real committed relationship with Him for a few years. Before that there was no relationship, only a handful of mumbled prayers when I needed something fixed. He has answered those half-hearted mumbled prayers from a decade ago. God was working when I did not even know who He is. And He is working all things for your good also, for His plan and will for you.
Something else that has greatly helped me get past hurtful things. Think of all the diversity of species God has created: all that is in the ocean, all the weird looking birds, the monkeys with hairless butts(those make me laugh)...this God, Creator of all diversity, the ONE true living God...He knows YOU. HE cares about YOU and loves YOU, and approves of you, and not for one second is He going to ask you to do something that is "dumb". He knows what we don't know(which is a lot). Really think about who He is, and who we belong to. So what if others say or do hurtful things to us...it becomes minor in light of Him.
I have to add: what is it to be a child of God? Isn't the "overcoming" in offering love where it is not deserved? Isn't that the action of God that changed everything in: He offered love to the undeserving.
Which is all.
