From the scripture , we see that there is a way Jesus Christ taught His disciples to pray. And the if we look at the context of this prayer closely, we will see where we have these words, "as it is in heaven, so be it on earth". Meaning that God always want us to seek His will and doings according to how it is in heaven.
So The Will of God is the number one in our prayers which helps deliver the answers to prayerers according to His will. And most importantly also, people need to learn how to pray with faith, because without faith, it is completely impossible to please God.
As a matter of fact, faith is the very engine that's facilitate speedy delivery of prayers, because when we completely have nothing to doubt, we create the existence of it already and it becomes totally real to us. Our prayers are answered by faith.
