[When the disciples talked to Jesus about problems in their prayer life, this is what he gave them – six short sentences of spiritual dynamite:

I don't think you could say more dangerous words than those found in the Lord's Prayer.  Here are the radical words I have been alluding to: “Your kingdom come, your will be done, on earth as it is in heaven” (Matthew 6:10).
I must admit that I don't always greet God's kingdom with delight.  There are things that I want in my life, and I not only want them, but I know how, when, and where I want them!  I want my life to be comfortable.  I want my schedule to be unobstructed and predictable.  I want the people around me to esteem and appreciate me.  I want control over the situations and relationships in my life.  I don't want to suffer.  I don't want to live without.
What I am saying is that I want my kingdom to come and my will to be done.
“Thy kingdom come” is a dangerous prayer, for it means the death of your own sovereignty.  It means your life will be shaped by the will of another.  It means that you will experience the messiness, discomfort, and difficulty of God's refining grace.  It means surrendering the center of your universe to the One who alone deserves to be there.  It means loving God above all else and your neighbor as yourself. It means finally living for the one glory that is truly glorious, the glory of God.
And it is only God's grace that can produce this kind of heart.
