And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.

People's New Testament

28:18 Spake unto them. To the whole assembly of five hundred brethren (1Co 15:6). A commission had been given long before to the twelve apostles (Mt 10:1-15), and also to the seventy, but it differed widely from the one now given. It confined the preaching to the Jews, and announced the kingdom of heaven as yet in the future. Now the preachers of Christ are sent, by the authority of the King, to make disciples of all nations. The old dispensation had ended with the cross. The new one had begun with the resurrection.

All power. Henceforth he was the King and Judge of the nations. The word is given denotes the source from whence he obtained his power, and implies that it was not inherent in the Son. Php 2:9 indicates that it was given to him after, and in consequence of, his voluntary humiliation; and 1Co 15:27, shows that it held in subjection to the Father. It was because the authority to rule the world had been placed in his hands that he issued his commands that it should be conquered.

Wesley's Notes

28:18 All power is given to me - Even as man. As God, he had all power from eternity.

Matthew Henry's Concise Commentary

28:16-20 This evangelist passes over other appearances of Christ, recorded by Luke and John, and hastens to the most solemn; one appointed before his death, and after his resurrection. All that see the Lord Jesus with an eye of faith, will worship him. Yet the faith of the sincere may be very weak and wavering. But Christ gave such convincing proofs of his resurrection, as made their faith to triumph over doubts. He now solemnly commissioned the apostles and his ministers to go forth among all nations. The salvation they were to preach, is a common salvation; whoever will, let him come, and take the benefit; all are welcome to Christ Jesus. Christianity is the religion of a sinner who applies for salvation from deserved wrath and from sin; he applies to the mercy of the Father, through the atonement of the incarnate Son, and by the sanctification of the Holy Spirit, and gives up himself to be the worshipper and servant of God, as the Father, Son, and Holy Ghost, three Persons but one God, in all his ordinances and commandments. Baptism is an outward sign of that inward washing, or sanctification of the Spirit, which seals and evidences the believer's justification. Let us examine ourselves, whether we really possess the inward and spiritual grace of a death unto sin, and a new birth unto righteousness, by which those who were the children of wrath become the children of God. Believers shall have the constant presence of their Lord always; all days, every day. There is no day, no hour of the day, in which our Lord Jesus is not present with his churches and with his ministers; if there were, in that day, that hour, they would be undone. The God of Israel, the Saviour, is sometimes a God that hideth himself, but never a God at a distance. To these precious words Amen is added. Even so, Lord Jesus, be thou with us and all thy people; cause thy face to shine upon us, that thy way may be known upon earth, thy saving health among all nations.
