Psalm 37:4 - "Delight thyself also in the LORD; and he shall give thee the desires of thine heart." - When we ask God for the desire of our heart we do not always get it. Why? Because we are not always delighting in God. As we Delight in the Lord our request will become less selfish and more selfless. This is when we WILL receive the desires of our heart, because our heart will desire to help others NOT ourselves.
