“Might their interest have had something to do with the jaw-dropping, eye-popping promises Jesus attached to prayer? ‘Ask and it will be given to you’ (Matt. 7:7, NIV). ‘If you believe, you will get anything you ask for in prayer’ (Matt. 21;22, NCV).”
Jesus never attached such power to other endeavors. ‘Plan and it will be given to you.’ ‘You will get anything you work for.’ Those words are not in the Bible. But these are–‘If you remain in me and follow my teachings, you can ask anything you want, and it will be given to you” (John 15:7, NCV)
