Revelation 2:26

And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations:

And - implying the close connection of the promise with the exhortation, Revelation 2:25.

And keepeth - `and he that keepeth:' alluding, as in Revelation 2:24, to Acts 15:28, end.

My works - in contrast to 'her (or their) works' (Revelation 2:22). The works which I command, the fruit of my Spirit.

Unto the end - (Matthew 24:13.) The image is from the race, wherein it is not enough to enter the lists: the runner must persevere to the end.

Give power, [ exousian (G1849)] - 'authority.'

Over the nations. At Christ's coming, the saints shall possess the kingdom "under the whole heaven" (Daniel 7:27): therefore over this earth (cf. Luke 19:17).
