Read: Matthew 6:9-13
Your kingdom come, your will be done, on earth as it is in heaven. (Matthew 6:10 ESV)
Jesus' spoke at length during his Sermon on the Mount about prayer, even demonstrating a very practical kind of way of praying for his followers. As such a hugely important aspect of the Christian life, I believe we can still model prayer after Christ's words. The second aspect of his prayer revolved around both the kingdom and will of God.
In the Old Testament people regularly referred to the Jews as the Kingdom of God. Jesus spent a lot of time speaking to that issue. The kingdom he referred to was not one of heritage or borders. Rather, God's kingdom was one of the soul. It was comprised of people following the heart of God.
Jesus told his people to pray for God to have His way among them. It was a way for them to intentionally set aside their own desires in recognition for the superiority of God's plan. It is the acknowledgement that for the Kingdom of God to be the reality for our lives that God Himself must be the king of our lives.
