For you, what's that mean that God IS reality? Reality for me are things that I can reach out and touch, or smell, or even see.
CS Lewis gives a great picture of the strength of reality of the Spiritual compared to the Material, in his space trilogy. Someone sees an angel as a sort of beam of light, which if you tried to look directly at it, it was invisible, but out the corner of your eye, it stood at an angle to the ground, yet, it was more like it was vertical, and the ground was askew.
Logically, reality is whatever God says it is, since he knows all things. But all things depend on him, not just for coming into being but also for its sustenance, or remaining 'in being'. They are real, only because he is real. They are not the standard for reality.
It's this life we are living though. Even in this life God can be seen, all in all. Which is why I don't understand the waiting for a next life when God is right here, right now.
It's this life we are aware of, at least.
The next life is more real than this vapor of existence we see now. There, we will see him as he is. Here, we live him as vessels, incomplete. There, finally complete. The 'waiting' is to see him as he is, and to be like him. It doesn't mean that we don't live him now.
