Hey I T. You are giving correct current scientific evidence, the universe is spreading out at an increasing rate. The logical result of this is not good for us or a logical God and if youre saying your theology is consistent with this then you may want to rethink it. If natural law is allowed to continue in its present direction then not too long from now everything will be almost infinitely separated. Every atom will exist as far from any other as possible. I would have to question any deity that would have planned and allowed that to occur. What is the point? This God would be capricious, inept, and insane from our perspective. Why build a universe that fails to be a purposefull universe?
The Bible says that God will abolish the current state of nature and reinstitute the perfect state it was intended to have. A universe that is an infinite expanse of dust is not in a Biblical future. The Bible does not get into as much detail about this as I would like but it is clear than everything is remade, "behold I make all things new". The Earth is burned to a crisp and then remade, perfectly. That is where heavens "headquarters will be. Since this does not allow for you always expanding universe I can just imagine the redaction that has taken place with revelations.
For the rest you are assuming that if God sat around and only made the universe a few billions years ago that is a problem. Philosophers have demonstrated that this is simply not true.
1. God exists independent of time. It has little or no effect or relevance on him. That is why the thousand years are a day and vice versa.
2. There was no time "before" the big bang that anyone had to wait out. Cosmology and Biblical cosmology both claim that God created time, matter, and space at the big bang. Time did not exist "before then".
3. It is also a logical IMPOSSABILITY that time is infinite. That is naturally incoherent self-refuting concept unless you appeal to fantasy and science fiction.
4. Even if time existed for eternity, and if God sat around for eternity and then decided to make everything, that is still not a problem. That would only mean something for a being with either limited time or ability. You can say you would not have done so yourself, but to say God should not have, is a meaningless statement.
So in summary the Bible's "In the beginning (time), God created the heavens (space), and the Earth (matter) is an accurate description of the best current cosmology and is consistent with an almost intuitive cosmological instinct in humans. If your theology suggests infinite time or an infinite universe then it might be right, or might be wrong but is certainly against known natural law and the most reliable current cosmology.
