Though incredibly huge, there are not an infinite number of stars in the universe. A limitless amount, by definition, implies more of these celestial objects are always being created such that no one would be able to count them all. The Bible, however, states that not only can God count them all he has given each of them a name!
He (God) counts the number of the stars; He calls them all by their names (Psalm 147:4, HBFV throughout).
Lift up your eyes on high, and behold, Who has created these things, Who brings out their host by number? He calls them all by names by the greatness of His might, for He is strong in power; not one fails (Isaiah 40:26).
The Fate of Everything
The state of the universe and its ultimate fate are hotly debated topics in the scientific community. Will the cosmos continue to expand forever? Is its fate to grow darker and colder until it finally "burns out" and becomes incapable of producing light or sustaining life?
Scripture declares our current physical universe will not expand forever nor will natural forces be allowed to determine its fate. It will continue to expand until the Lord, in the not too distant future, decides it has served its purpose. He then will create, through his infinite power, a new universe (and new earth) to replace what we now have.
Of old You have laid the foundation of the earth, and the heavens are the work of Your hands. They shall perish, but You shall endure; yea, all of them shall become old like a garment; like a vesture You shall change them, and they shall be changed (Psalm 102:25 - 26, see also Hebrews 1:10 - 12).
And all the host of the heavens shall be dissolved, and the heavens shall be rolled up like a scroll; and all their host shall fall down, as a leaf falls off from the vine, and as the falling fig from the fig tree (Isaiah 34:4).
Lift up your eyes to the heavens, and look upon the earth beneath; for the heavens shall vanish away like smoke, and the earth shall become old like a garment . . . (Isaiah 51:6).
For behold, I create new heavens and a new earth. And the former things will not be remembered, nor come to mind (Isaiah 65:17).
Looking forward to and striving for the coming of the day of God, during which the heavens, being on fire, shall be destroyed, and the elements, burning with intense heat, shall melt? But according to His promise, we look forward to a new heaven and a new earth, in which righteousness dwells (2Peter 3:12 - 13).
Then I saw a new heaven and a new earth (a new universe!); for the first heaven and the first earth were passed away . . . (Revelation 21:1).
It may be, however, that the new universe God creates will be allowed infinite expansion as it will be perfect and sinless.
