Chapter 24 of Matthew concerns Jesus telling his disciples of the times spoken of by Daniel the prophet, the ‘eschatological’ times which means the coming of a new age or ‘eschaton.’ Jesus warns of calamities and a great tribulation that will precede the coming of the Son of Man.
Matthew 24: 9-14 “Then they will hand you over to persecution, and they will kill you. You will be hated by all nations because of My Name. And then many will be led into sin; they will betray and hate one another. Many false prophets will arise and deceive many; and because of the increase of evildoing, the love of many will grow cold. But the one who perseveres to the end will be saved. And this gospel of the kingdom will be preached throughout the world as a witness to all nations, and then the end will come.”
The great commissioning of the Apostles by Jesus (and commissioned now to us) to go into the world and baptize in His Name.
Matthew 28: 17-20 When they (disciples) saw Him, they worshiped, but they doubted. Then Jesus approached and said to them, “All power in heaven and on earth has been given to Me. Go, therefore, and make disciples of all nations, baptizing them in the Name of the Father, and of the Son, and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, until the end of the age.”
