And he that overcometh - notes on Revelation 2:7.
And keepeth my works unto the end - The works that I command and that I require, to the end of his life. Compare John 13:1.
To him will I give power over the nations - The evident meaning of what is said here, and in the next verse, is, that in accordance with the uniform promise made to the redeemed in the New Testament, they would partake of the final triumph anal glory of the Saviour, and be associated with him. It is not said that they would have exclusive power over the nations, or that they would hold offices of trust under him during a personal reign on the earth; but the meaning is, that they would be associated with him in his future glory. Compare the Romans 8:17 note; 1-Corinthians 6:2-3 notes.

Power over the nations - Every witness of Christ has power to confute and confound all the false doctrines and maxims of the nations of the world, for Christianity shall at last rule over all; the kingdom of Christ will come, and the kingdoms of this world become the kingdoms of our God and of his Christ.

(20) And he that overcometh, and keepeth my works unto the end, to him will I give (21) power over the nations:
(20) The conclusion, in which Christ assures to his servants the communion of his kingdom and glory, in this verse, and that following: and commands a holy attention in the last verse (Revelation 2:29).
(21) That is, I will make him a king, by communion with me, and my fellow heir, as it is promised; (Matthew 19:28, Matthew 25:34) (Romans 8:17; 1-Corinthians 6:3; Ephesians 2:6; 2-Timothy 2:12).

And he that overcometh,.... Jezebel and her idolatries, her children, and all that commit adultery with her; such as are not drawn into the same evil practices with them, but bravely stand their ground against the Romish antichrist and his followers, and bear their testimony against his impious doctrines and idolatrous practices:
and keepeth my works unto the end; either of life, or of this church state, or of time, when Christ will personally appear, even at the end of the world; and by his works are meant, not the works which were done by him, as his miracles and works of mercy to the souls and bodies of men, and works of righteousness in obedience to the law, and the work of redemption and salvation; though these are works to be observed, and kept in view, and to be preserved in memory, and for the encouragement of faith and hope; but the works which are commanded, and required by Christ to be done by his people; as the public work of the ministry, by the preachers of the Gospel; and every private work, both internal and external, as the work of faith, the labour of love, and every act of obedience, which is constantly to be discharged. The Arabic version reads, "and keepeth my words and my works"; things both relating to doctrine and practice:
to him will I give power over the nations; or Gentiles, the Papists; so called because of the Pagan notions and worship introduced by them; and because they consist of many nations, tongues, and people, who are deceived, and drawn into idolatry by them: and this power over them may be understood in a spiritual sense, through the preaching of the Gospel, which being attended with the power of God, is the means of converting sinners, and so of weakening the kingdom of Satan, and of antichrist; and which had its fulfilment, at least in part, at the time of the Reformation, and onward, and will have still a greater accomplishment in the spiritual reign of Christ and his people, under the Philadelphian church state; and it may also design the temporal power which the saints shall have over antichrist, when they shall take away his dominion, and consume and destroy it, and the kingdom and the dominion under the whole heaven shall be given to the saints of the most High; Daniel 7:25.

And--implying the close connection of the promise to the conqueror that follows, with the preceding exhortation, Revelation 2:25.
and keepeth--Greek, "and he that keepeth." Compare the same word in the passage already alluded to by the Lord, Acts 15:28-29, end.
my works--in contrast to "her (English Version, 'their') works" (Revelation 2:22). The works which I command and which are the fruit of My Spirit.
unto the end-- (Matthew 24:13). The image is perhaps from the race, wherein it is not enough to enter the lists, but the runner must persevere to the end.
give power--Greek, "authority."
over the nations--at Christ's coming the saints shall possess the kingdom "under the whole heaven"; therefore over this earth; compare Luke 19:17, "have thou authority [the same word as here] over ten cities."

By works - Those which I have commanded. To him will I give power over the nations - That is, I will give him to share with me in that glorious victory which the Father hath promised me over all the nations who as yet resist me, Psalm 2:8-9.
