Patience and Expectation are important when it comes to prayer. First off, you must have patience when waiting for a prayer to be answered. It may not be God's time for it yet. Second, You must enter into prayer with an expectation that if what you're praying for is in God's will, that IT WILL HAPPEN. So many people (Me included several times before) after they're done praying and seeing that nothing has happened right away say "It's not going to happen". People, just keep praying about it! Whatever you ask for (if it's in God's Will) will be given to you!
