The German theologian Karl Barth believed that the second coming was a parousia… a revelation of what already is but that we are blind to. He believed that it will be like the pulling back of the veil to reveal what already is true.
What I take Barth to mean is that the second coming is a metaphor for humanity to finally see the connectivity in all things, the unity of all things, the All in the all.
Our unity with all races. Our unity with all sexualities. Our unity with all genders. Our unity with all people. Our unity with all things.
The ancient cry, “maranatha” (Come, Lord Jesus)… even if we don’t subscribe to a Christian theology… we can cry today: “We want to see and live the unity of all things. Now!”
