the end comes, when he will deliver up the Kingdom to God, even the Father; when he will have abolished all rule and all authority and power.
Context / meaning
1 Corinthians 15 [20.] But now Christ has been raised from the dead. He became the first fruits of those who are asleep. For since death came by man, the resurrection of the dead also came by man. For as in Adam all die, so also in Christ all will be made alive. But each in his own order: Christ the first fruits, then those who are Christ’s, at his coming. Then the end comes, when he will deliver up the Kingdom to God, even the Father; when he will have abolished all rule and all authority and power.
1 Corinthians 15 [25.] For he must reign until he has put all his enemies under his feet. The last enemy that will be abolished is death. For, “He put all things in subjection under his feet.”[a] But when he says, “All things are put in subjection”, it is evident that he is excepted who subjected all things to him. When 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. Or 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?
