I believe Jesus said, "Ask and yeh shall receive..." It amazing how the universe works like that!
I like Bible verses so lets explore what is being said there.
I will attempt to clarify, as best I can, using what is said in other parts of the Bible.
The Bible cannot be understood through casual reading, that is for sure.
John 14:14 Context
11Believe me that I am in the Father, and the Father in me (God is 3 persons unified as 1; similar to a marriage): or else believe me for the very works' sake(because of what you've seen).
12Verily, verily, I say unto you, He that believeth on me (verse 11, I am יְהֹוָה = Yeh-ho-vaw'), the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father ("I and my father are one" -John 10:30)
13And whatsoever ye shall ask in my name (in the name of Salvation*, for Salvation is his name), that will I do, that the Father may be glorified in the Son.
14If ye shall ask any thing in my name, I will do it.
15If ye love me, keep my commandments.
16And I will pray the Father, and he shall give you another Comforter(who?), that he may abide with you for ever;
17Even the Spirit of truth(Word); whom the world cannot receive (Jesus), because it seeth him not(they have eyes but do not see), neither knoweth him: but ye know him; for he dwelleth with you (Jesus), and shall be in you (Jesus declares that he and the Spirit are one & so also shall you be one when the Spirit of God dwells in you: John 17:22)(You will not become God, you will be united with God; this "oneness" is called "new creation")
*16And he (the LORD) saw that there was no man, and wondered that there was no intercessor(these guys are in trouble!): therefore his arm brought salvation(Jesus) unto him(man)(John 6:38); and his righteousness, it sustained him(sustained man, God is in no need of sustenance).
