It’s often marveled at, the idea that God would make himself vulnerable by coming down to Earth in the form of Christ. I agree that it’s an amazing thing that God made himself vulnerable. But I think that this assessment is off by several thousand years.
Taking on the flesh of Jesus was just an object lesson, a personification, of what had gone on before. In the garden of Eden, God made himself vulnerable. God loved us, and he opened himself up to being hurt by us. He trusted us, and he opened himself up to being betrayed by us. He tried to teach us, and he opened himself up to the possibility of us missing the point.
Can you imagine a knight taking a hammer to his armor, and saying “I’d like to make a chink in it, right here? I’ll choose this weakness.”
Or a tank driver. Going at his tank, saying “I’ve modified things. Now, if somebody shoots us right here, our tank is going to blow up.”
What God did is more over the top. Because he is so much greater than a knight or a tank driver. He set the stars in motion. He created the black holes. He started the stars burning. He set the planets spinning. He created space-time. He made us.
And then he made himself vulnerable to us.
