Requirement for an answered prayer.

-You should be a true believer (i.e. a person who has accepted Jesus as his Lord and savior and who worships God in truth and in spirit, not the hypocrite type of believer).

-You should be forgiving (i.e. holding no grudge against your neighbor).

-You should be humble (i.e. don't think you deserve whatever you ask for rather see yourself as worthless and privileged to have the chance to stand before God).

-Finally, you should know the right way to pray (i.e. don't pray anyhow because God doesn't listen to anyhow prayers. So let your prayer be in line with the word of God and should be systematic, genuine and well organised).

Approximately, more than a thousand of people pray every second including non-Christian believers. So what I think is that God first listen to those with the right requirement and answers them before attending to the rest without these requirements. That's why many people don't get their prayers answered even after spending hours in praying and going for prayers in different prayer camps. First of all, you can't blame God for not answering your prayers because everybody prays and for your prayers to be different you need to know the requirement for an answered prayer and follow suit.
