This then, is how you should pray:

Our Father in heaven.
Hallowed be your name,
your kingdom come,
your will be done
on earth as it is in heaven,
Give us today our daily bread
Forgive us our debts,
as we also have forgiven our debtors.
And lead us not into temptation,
but deliver us from the evil one.
Matthew 6:9-13

When you don't know what to pray, just pray 'Our Lord's Prayer'.

I can recite this prayer in 3 languages. However, what use is that if I don't pray at all?
