Before · 1 Corinthians 15:27–28
27For, “He put all things in subjection under his feet.” But when he says, “All things are put in subjection”, it is evident that he is excepted who subjected all things to him. 28When all things have been subjected to him, then the Son will also himself be subjected to him who subjected all things to him, that God may be all in all.
29Or else what will they do who are baptized for the dead? If the dead aren’t raised at all, why then are they baptized for the dead?
