Wednesday of the Twenty-seventh Week in Ordinary Time [I]

Reading Jonah 4:1-11
Gospel Luke 11:1-4

"Father, hallowed by your Name, your Kingdom come."

Every Christian knows by heart the 'Our Father': the only prayer that Jesus taught to His followers. But the 'Our Father' that we know in our hearts—which we pray at every Mass before receiving Holy Communion, and which we pray several times throughout the course of a rosary—is not exactly the 'Our Father' that we hear Jesus teach in today's Gospel passage.
The version of the 'Our Father' that Luke records for us is shorter than the version that we know by heart. Maybe this shorter version is the first version that Jesus taught to his followers, much the same way that a teacher introduces just the key points of a lesson first, and then later fleshes it out some more.
In this shorter version of the 'Our Father', there are three petitions that Jesus teaches us to pray. In the silence following Holy Communion, or after Mass, or in your home, read and pray this shorter version, and see what the three petitions are. What are the three things that Jesus teaches us to ask for from our Heavenly Father?
