Thematic Bible: The last enemy that shall be destroyed

And because the children are flesh and blood, he took a body himself and became like them; so that by his death he might put an end to him who had the power of death, that is to say, the Evil One; And let those who all their lives were in chains because of their fear of death, go free.

For his rule will go on till he has put all those who are against him under his feet. The last power to come to an end is death. For, as it says, He has put all things under his feet. But when he says, All things are put under him, it is clear that it is not said about him who put all things under him. read more.
And when all things have been put under him, then will the Son himself be under him who put all things under him, so that God may be all in all.
