Hey, Nancy, believing that God is IN everything is a panentheist belief. A pantheist, such as myself, believes that God IS everything.
I think Now includes the past, present, and future. It depends on whether you are viewing life from the perception of linear time, or timelessness. All things are happening Now.
Heaven can be now if one stops judging things as right and wrong, good and bad. I have done it before, but who can stay in that place? The things in this world shout that they are to be judged. Death, pain, sickness, war, cruelty-these things are loud! They hurt. But, you know, I can't imagine living in a world where there was none of this. The story is interesting. Why else do we watch movies, play video games, read books? What would happen in a world without death, war, pain, sickness? Well, for one, we would stay the same, we would not change, we would not grow-we would never know healing or forgiveness or compassion again.
