When you write out a grocery list, whether physically/on paper, or mentally/in your head, whatever is on that list, are your expectations for you to receive what you want on that list. You are in control of that list. Therefore, whatever you chose to get, not get, or add to that list is up to you, based on what you have to spend.
When you pray and ask God for something, you may have a prayer list of things that you’re asking for. Your expectations of God is to give you what you ask for from that prayer list. Just like your grocery list, you are in control of that prayer list. Therefore, whatever you chose to get, not get, or add to your prayer list is up to you, based on your faith, and lining up with the will of God.
You are in control of what you want or don’t want. God gave you power. Your faith is your spending money — your power. He said for you to ask him. So, those things that you want, and they align with His word and His will, pray — and believing, and you will receive it.

Luke 19:19 (KJV) – behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
I John 5:15 (KJV) – and if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
