Pete pointed this out to me this morning, and I thought it was really compelling. It's from a Lenten devotional book by Calvin Miller, called "The Christ of Easter."
People die with purpose when they have clearly marked the reason they were given life. Jesus existed to do the will of God.
Since doing what his Father wanted would bring pleasure to the both of them, Christ was thus occupied with the pleasure of God. Jesus served this single passion: to glorify God – to live to serve him, to please him. He faced every mortal decision at every juncture of his life with only one concern: how will my decision affect my Father.
Seeing that such a passion owned Christ, how can we become Christlike? We must seek what he sought. Our chief duty is to glorify God and to enjoy him forever. Think of how your world would change if in every moment of decision, you did only those things that you knew would bring glory to the Son of God. In such a life there would be power!
In such a life there would also be simplicity. To want only one thing is to achieve purity of heart. To want only one thing puts to silence the competition of your inner appetites. To want only one thing silences the quarrel of trying to serve both Jesus and your own need for power.
Glorify God! Let this be your reason to live! You will then love God. And the simplicity of loving him so singularly will help you to discover and love yourself as well.
