“Truly I tell you, whatever you bind on earth will be bound in heaven,
and whatever you loose on earth will be loosed in heaven. Again, 
truly I tell you that if two of you on earth agree about anything they
ask for, it will be done for them by my Father in heaven. For where 
two or three gather in my name, there am I with them.”

the door will be opened to you. For everyone who asks receives; the 
one who seeks finds; and to the one who knocks, the door will be 
opened. Which of you, if your 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!”
