Heathen,
I don't mean to say that Christ has abandoned the earth. I do think that the word presence is more easily understood than coming. He cannot return in a literal sense, but he is and always has been present. The change that needs to be made is in human consciousness. Christ said he was the vine and we are the branches, as long as we remain in union with him. So we are already part of the divine if we choose to be right now.
I still find myself wanting someone (Christ) to come and magically make everything all right, but I don't believe that is what he meant by the statements you quoted. All we can do is choose to live in the present and take care of the small, but important role that each of us plays in this moment. This is where all life takes place in, the present. If we take care of our inner selves, we will also choose to take care of this planet.
