It is totally true due to the fact that it helps us to know how to approach to God. Even though, it does not mean that we need to say it word by word. We can take the pattern and modify it with what it is in our hearts. For instance, in the first paragraph says: "Our father who art in heaven, hallowed be thy name". We can take that pattern and say: Oh God almighty, let your name be lifted high as we pray". The pattern is still evidenced but with other words.
