Gill's and Dary's Commentaries on Matthew 28:18-19
Gill's Exposition of the Entire Bible
18And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
And Jesus came and spake unto them,.... To the eleven disciples and apostles; for though there might be so large a number as before observed, yet the following words were only spoken to the apostles:
saying, all power is given unto me in heaven and in earth; which is to be understood of him, not as God, who has the same original and underived power and authority over all creatures, and things in heaven and earth, as the Father has; but as mediator, to whom all things are delivered by the Father; and not of a power of doing this, or the other thing, or of omnipotence, being the Almighty; nor of doing miracles, and forgiving sins, which he had, and exercised before his death and resurrection, but of governing: he was king before, but his kingdom was not with observation; but now he was declared, and made manifest, to be both Lord and Christ; he had "all" power and authority for the settling the affairs of his church and kingdom, to appoint offices and officers in it, and, to bestow gifts upon men, to qualify them for the same, and to institute ordinances to be observed till his second coming: and this power of his reached to things in heaven; he having the angels in heaven subject to him, as ministering spirits to be sent forth by him at his pleasure; and all the gifts of the Spirit to dispose of as he thought good; and to things on earth, not only to the saints, whose King he is, and who are made willing to serve him; but to all flesh, to kings and princes, who rule and reign by him; and even to all the wicked of the world, who in some shape or another are made to subserve the ends of his mediatorial kingdom and government: and this is not usurped power, but what is given him, and what he has a right to exercise; having finished sin, abolished death, overcome the world, and destroyed the devil; and must reign till all enemies are subject to him: and this he says, and it was necessary to say it at this time, partly on account of his late sufferings and death, which were attended with weakness and reproach; and partly on account of the following commission he gives to his disciples, that it might be seen and believed, he had power and authority sufficient to give them such an one; as also to animate and encourage them under all the weakness, contempt, and persecution that should attend them in their ministry.
Darby's Bible Synopsis
As I have already said, Jesus connects Himself with His former work among the poor of the flock, afar from the seat of Jewish tradition, and from the temple, and from all that linked the people with God according to the old covenant. He appoints His disciples to meet Him there, and there they find Him and recognise Him; and it is there, in this former scene of the labours of Christ, according to Isaiah 8 and 9, that they receive their commission from Him. Hence we have not the ascension of Christ at all in this Gospel, but all power is given unto Him in heaven and in earth, and accordingly the commission given to His disciples extends to all nations (Gentiles). To them they were to proclaim His rights, and make disciples of them.
It was not however the name of the Lord only, nor in connection with His throne at Jerusalem. Lord of heaven and earth, His disciples were to proclaim Him throughout all nations, founding their doctrine on the confession of the Father, of the Son, and of the Holy Ghost. They were to teach, not the law, but the precepts of Jesus. He would be with them, with the disciples who thus confessed Him, unto the end of the age. It is this which connects all that will be accomplished until Christ sits upon the great white throne with the testimony that He Himself rendered on the earth in the midst of Israel. It is the testimony of the kingdom, and of its Head, once rejected by a people that knew Him not. It links the testimony to the nations with a remnant in Israel owning Jesus as Messiah but now risen from the dead, as He had said, but not to a Christ known as ascended on high. Nor does it present Jesus alone, nor Jehovah, as any longer the subject of testimony, but the revelation of Father, Son, and Holy Ghost as the holy name by which the nations were connected with God.
