Desire

When someone has a desire it usually means they want to do something. Desire is not something that can be given by anyone else in the real world. Your desire comes from the inside.  If there is something you want to do, it is probably not because somebody is holding a gun to your head. You just want to do it.

If you decide you want to improve, if you want a meaningful relationship or more fulfilling work, if you want a rich spiritual life or a healthier body, then the desire must come from your own heart. Nobody can make you want those things. They can support you and even inspire you, but only you can make it happen.
This is why the Word of God gives us instructions on and about our desires. I believe it is a 4 step process according to the scripture.

(1) You must first respect and honor the Lord.Psalm 145:19 says, "He will fulfill the desire of them that fear him: he also will hear their cry, and will save them."
(2) You must live holy and righteous in His sight.
Proverbs 10:24 "The fear of the wicked, it shall come upon him: but the desire of the righteous shall be granted."

(3) You must have faith when you pray.
Mark 11:24 "Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them."

(4) You must realize that God knows and has already made provision.
1 John 5:15 "And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him."

One last verse:
Psalm 20:4 HCSB "May He give you what your heart desires and fulfill your whole purpose.^"
