“To him that ouercommeth, will I graunt to sit with mee in my throne, euen as I also ouercame, and am set downe with my Father in his throne.”
1611 King James Version (KJV)
3:21 I will give him to sit with me on my throne - In unspeakable happiness and glory. Elsewhere, heaven itself is termed the throne of God: but this throne is in heaven.
Re 3:21 To him that overcometh will I grant to sit with me in my throne. He shall reign with Christ; that is, as a coadjutor of Christ. As I also overcame, and am set down with my Father in his throne. As the result of his overcoming God exalted him to be a Prince and a Saviour (Ac 5:31), and to sit at the right hand of the Majesty of the heavens (Heb 8:1). As he was exalted, so he will exalt all his brethren who win the victory over sin and temptation.
