This beautiful prayer [from John 17] for union is from Jesus’ Last Supper address to his disciples. It might be the highest level of mystical teaching in the entire New Testament. Here Jesus connects everything: he in his Father, the Father in you, you in God, God in him, God in the world, and you in the world. It’s all one.

I think this is the core realization of every saint. Saints see things in their connectedness and wholeness. They don’t see things as separate. It’s all one, and yet like the Trinity, it is also different. What you do to another, you do to yourself; how you love yourself is how you love your neighbor; how you love God is how you love yourself; how you love yourself is how you love God. How you do anything is how you do everything.

Faith is not simply seeing things at their visible, surface level, but recognizing their deepest meaning. To be a person of faith means we see things—people, animals, plants, the earth—as inherently connected to God, connected to ourselves, and therefore, absolutely worthy of love and dignity. That’s what Jesus is praying for: that we could see things in their unity, in their connectedness.
