True prayer, which is the medium of miracles, and is how you "ask", occurs in the heart, not in words necessarily. There is a guy who performs a lot of miracles who teaches to "pray with your whole heart". The heart has to be experiencing love, in order to be experiencing wholeness. Whatever is "in your heart", that is what you are asking for. Being "pure of heart" is important.
God doesn't care about your words or whether they really match what you are asking for or not. Your asking actually happens in the heart in terms of what it is you "want" or feel a "genuine" desire for. And typically that means that your prayer has to be aligned with God's Will and reflect His Laws in order to produce a miracle.
I was trying to do miracles and had a moment of feeling love and Holy Spirit excitedly said to me "that is all you need!" - the love, in the heart, heartfelt prayers. The intellect is good at saying words and all that, but the heart has to be involved. Words without the heart part, does nothing. Heart part with words does something. Heart part without words does something. The heart is all that's needed.
Finding enough LOVE in your heart to pray this way... it's not exactly easy if you are not "naturally" in a play of significant love. You may have to really stretch yourself and dig deep. Really go within and not only receive love (can only give the miracles you have received) and create as much feeling of love as you can, first, before you pray. And having this much love for total strangers is not easy, if you still have blocks to love or judgements to undo. "One instant of love without fear is all that's required that all of this should happen".
Here it is in Jesus's own words:
"M-21.1. Strictly speaking, words play no part at all in healing. 2 The motivating factor is prayer, or asking. 3 What you ask for you receive. 4 But this refers to the prayer of the heart, not to the words you use in praying. 5 Sometimes the words and the prayer are contradictory; sometimes they agree. 6 It does not matter. 7 God does not understand words, for they were made by separated minds to keep them in the illusion of separation."
