To him that overcometh - See the notes on Revelation 2:7.
Will I grant to sit with me in my throne - That is, they will share his honors and his triumphs. See the notes on Revelation 2:26-27; compare the notes on Romans 8:17.
Even as I also overcame - As I gained a victory over the world, and over the power of the tempter. As the reward of this, he is exalted to the throne of the universe Philippians 2:6-11, and in these honors, achieved by their great and glorious Head, all the redeemed will share.
And am set down with my Father in his throne - Compare the notes on Philippians 2:6-11. That is, he has dominion over the universe. All things are put under his feet, and in the strictest unison and with perfect harmony he is united with the Father in administering the affairs of all worlds. The dominion of the Father is that of the Son - that of the Son is that of the Father; for they are one. See the notes on John 5:19; compare the Ephesians 1:20-22 notes; 1 Corinthians 15:24-28 notes.
