For the moment, let’s leave Jesus or Christianity out of the picture. What if you tried to just believe in God in general? What if you just tried to live a good life and pray to him? How would you get into a relationship with a God like that? Wouldn’t that be exploitation? God wouldn’t change—you would have to do all the submitting, all the repenting, make all the sacrifices.
But Christianity is different. Jesus Christ lost his glory and became mortal and died for us. In Jesus God says, “I will adjust to you. I will sacrifice for you. First I will give up my glory and immortality in becoming human in the Incarnation. Then I will give up all light and joy and my very life in the Atonement.”
He was nailed fast to the cross so he could not move. How is that for giving up your freedom? Christianity is the only religion that claims God gave up his freedom so we could experience the ultimate freedom—from evil and death itself. Therefore, you can trust him. He sacrificed his independence for you, so you can sacrifice yours for him. And when you do, you will find that it is the ultimate, infinitely liberating constraint. “If the Son sets you free, you will be free indeed” (John 8:36).
