Isaiah 9:7 says.
Of the increase of his government and peace there shall be no end
But 1 Cor. 15 says.
** Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power. For he must reign, till he hath put all enemies under his feet. The last enemy that shall be destroyed is death. For he hath put all things under his feet. But when he saith all things are put under him, it is manifest that he is excepted, which did put all things under him. And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.** (Verses 24 to 28.)
So is that the end of increase?
Is that the end of creation?
No more inhabited planets like this one?
No more erring mortals in need of salvation?
No more children born anywhere, in all the universe?
