When exactly is the end?
"Look! I am with you all the days until the conclusion of the system of things." Matt 28:20
24 Next, the end, when he hands over the kingdom to his God and Father, when he has brought to nothing all government and all authority and power. 25 For he must rule as king until [God] has put all enemies under his feet. 26 As the last enemy, death is to be brought to nothing. 27 For [God] “subjected all things under his feet.” But when he says that ‘all things have been subjected,’ it is evident that it is with the exception of the one who subjected all things to him. 28 But when all things will have been subjected to him, then the Son himself will also subject himself to the One who subjected all things to him, that God may be all things to everyone. 1Cor15:24-28
