You have to quote the terms of the contract

 You will seek me and find me when you seek me with all your heart. (Jeremiah 29:12-13 NIV)

 For a good prayer life, one of the main things you need to know is God’s Word. Faith grows by faithful study of His Word. “Faith cometh by hearing the Word of God.” Even though God can answer anyway, you’ll find that a reading of God’s Word first will inspire you and give you more faith for your prayers.
 God has made promises in His Word, and when you pray, you should bring those promises with you to remind Him. When you remind God of His Word, it shows you have faith in it. And it’s a positive declaration of your faith and your knowledge of the Word which pleases Him.
 You have to quote the terms of the contract (the Bible) to the contract maker (God), and hold Him to it. So remind Him of it, cling to His promises, memorize and quote them, and never doubt for a moment that God is going to answer—and He will!
 So the next time you really need His help and are on the spot, call on the Lord and His power. Jesus never fails! He always answers when we stir ourselves to call upon Him with a whole heart. —D. B. Berg [1]

 "Prayer is a surge of the heart, it is a simple look turned toward heaven, it is a cry of recognition and of love, embracing both trial and joy." —St. Therese of Lisieux
