O Key of David

I like this Antiphon but I am not so sure I like the image of Jesus as a key! However, here is the antiphon:
O Key of David and scepter of the house of Israel, you open so that no one else can close again, you close so that no person can open: come, and lead the captive from prison, free those who sit in darkness and the shadow of death.

I hope you have time to reflect on this antiphon which has many ways of speaking to what is happening in our world and in our own souls. I do like the image of God opening what no one can close again and closing at the same time so that no person can open; I suspect that is the deepest part of us that belongs to God alone.
