The only prayer he gave word for word — and it is short on purpose.
His disciples asked Jesus to teach them to pray, and he answered with a prayer that takes thirty seconds. In Matthew it comes straight after a warning against "vain repetitions", from people who think they will be heard for their much speaking.
Here is Matthew's full text, one line at a time, and what each line asks.
Pray like this: 'Our Father in heaven, may your name be kept holy.
Calling God "Father" in prayer was not the usual way, and Jesus makes it the starting point for every disciple. And it is "our", not "my": the whole prayer is plural. Nobody prays the Lord's Prayer alone, even when they are alone — it asks for our bread, our forgiveness, our protection.
Half the prayer is about God — the name, the Kingdom, the will — before it reaches any personal request. And when the requests come, they are modest: bread for today, not for the month; forgiveness; not falling. It is a prayer for someone living one day at a time.
The only line Jesus comments on afterwards is the one about forgiveness: "For if you forgive men their trespasses, your heavenly Father will also forgive you" (Matthew 6:14). Of everything the prayer asks for, that is the one he goes out of his way to underline.
The Lord's Prayer is the prayer he gave; Walking with Jesus is made of the rest of what he said. One teaching a day, with the moment around it, a short reflection, a prayer and one thing to carry into the day.
It is a one-time purchase, about five minutes a morning, and it never asks you to catch up on days you missed.
