Why should we pray to God?

I’m not talking about prayers asking for help or to solve problems.

I’m just talking about prayers that your were taught at young age at church or some other religious place. Maybe you know some beautiful prayers that your repeat every evening before you go to sleep where you thank God for this and that…

To make the context clear my question should be rephrased: Why would God want us to pray?

It is stated in most major religions that God loves everyone no matter what. Then it doesn’t matter if we pray or not, he wouldn’t judge us by it anyways.

Is this a paradox or what?
