Prayer can be a tricky thing, because there are passages that say do not doubt and believe you have received whatever you ask for and you will, but then Jesus prayed 'Not my will by thy will be done.' Ultimately, we can't tell God what to do. He will accomplish, in our lives, whatever He wants to accomplish. God is God and we are not.
When you live by God’s Word, your life works. When you live without God’s Word, life doesn’t work. God’s Word builds you up, feeds your soul, and gives you strength, direction, guidance, hope, encouragement, and faith. Remember that He gave you His Word so that you would know Him and the way He wants You to live.
