There's a right manner by which we are meant to pray.When we pray we should avoid vain repetitions. God doesn't need to hear us say prayers in a particular pattern over and over again before our prayers reaches him. This is why it is irrelevant making prayers that consists of the same phrases continuously whereas God hears us the first time we made the prayers.
The human mind is full of malice, hatred and some people don’t even have faith. How do you expect your prayers to be answered when you don’t have faith in whom you are praying to?
Why do our prayers sometimes not get answered? This is simple and straightforward. The human heart is full of so many evil things and that is why they have as well turned the world to an evil place. Our prayers mostly don’t get answered because our hearts are not pure. I wish we could just use our hands to open the heart.
If there is anyone who ever told you that his prayers are not answered, ask the person what he has on his mind and if he or she is truthful enough to reveal it to you, you will find out that he is the actual cause why his prayers are not answered by God. I’m sure we all cannot deny this and the fact that our hearts are pure does not mean that the heart of every other person is pure. Matthew 15:19 says, For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander.
