"And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. For everyone who asks receives; everyone who seeks finds; and to those who knock it shall be opened." Luke 11:9-10
Here's a news flash: you already have all the love, peace, joy, and abundance that you could ever imagine! It's your birthright as a magnificent, divine child of God. All you have to do is choose these things. Just claim them. They are already yours. If you are not experiencing one or more of them, it's only because you're not choosing them. You don't have to ask for them.
So when it comes to asking, ask for something material. Why not? You have everything else!
