"Again, I tell you that if two of you on earth agree about anything you ask for, it will be done for you by my Father in heaven. (Matt 18:19 NIV)

This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us.  And if we know that he hears us-- whatever we ask-- we know that we have what we asked of him.(I Jn 5:14-15  NIV)

"Ask and it will be given to you; seek and you will find; knock and the door will be opened to you.  For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened.  "Which of you, if his son asks for bread, will give him a stone?  Or if he asks for a fish, will give him a snake?   If you, then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give good gifts to those who ask him!   (Matt 7:7-11 NIV)
