He chooses to follow his honest conviction against the flow of the world and what it values, rebelling against what he is told is his new truth, and instead fights to find who he is. His conscience leads him to find his true identity.
So do you choose to follow that thread of conviction you inherently know to be right, though it goes against what makes you comfortable? Do you instead adhere to the stickiness of God's word and rule - fighting against the lower nature? The nature that tends to war against God and separates us from His goodness...
Jason Bourne is in all of us. He is a fighter, and could carry his training to great exploits, doing what few others could do... But though he's been brainwashed, the truth remains in a voice inside his head. "You were not meant for this. This is not life." Just like him, we have that choice, and we can choose to ignore that voice, or instead follow it and become aliens, join a group of people who are despised for their beliefs and standards... Follow the world, or your purpose, which is in God alone.
What if it means giving up what you think means the most to you? Your reputation, your job, your friends, your pride?
God will wreck your life, and send you on the run. Don't believe it? Look at those who were closest to Jesus on this earth. They followed His example, and were imprisoned, tortured and murdered. Yet still they counted it all gain. Look at the stories of people beyond the typical American Christian, in history's chronicles, and today around the world there still are disciples of Christ laying down their lives like He did.
But to them, it is worth it. They know that to obey the world, they would be rejecting a higher authority, a God who is worth dying for. Yes, it is hard, I know. Sometimes doubt nags my mind, and I wonder at the cost. Then I remember the scars that were taken undeservedly so that I could have life.
To be who God purposed you to be may not seem as exciting, perhaps it may turn out to be very tough, but think of who you live for, and why.
So the question: Jason Bourne or David Webb? Who will you be?
Are you going to follow the truth or what others tell you is acceptable?
Find who you are. The rest will follow.
