A Father listens and cares for his own children. You are born into this world to your earthly father. You must be born again into the family of God, by coming to the Lord, humbly and asking Him for the forgiveness of your sins. Everyone sins! No one is exempt (expect, of course, Jesus Christ). Jesus came to this earth to redeem His creation back to Him. By acknowledging God for Who He is and humbling yourself before Him and recognizing He is the ONLY one who can forgive you of your sins, you become a part of His family, thus a child of God. Then and only then will your prayers have power.
Keeping in mind the praying to God is not reciting some written prayer that isn't from your heart. You don't come before Him reading (or reciting) a prayer that you say over and over. There is no meaning in that. God didn't create robots. He created human beings, and He desires a real relationship with you not some scripted time.
Just think about who you're speaking to the next time you set your mind to pray. God is anxiously waiting to hear from you. Do you go before your friends and loved ones with pre-written words or words you've memorized? Do you rush in before them, spew out some words and run off? That's not a relationship. A good relationship is when you give of your time. That's what God wants in your prayer life. Come before the Lord prepared to meet the Prince of Peace and watch the blessings come.
