This verse contains a succession of 4 historical realities that are described in the next for chapters (4, 5, 6, and 7).
• The first historical reality is the victory of Jesus (chapter 4).
• His victory is followed by His enthronement (chapter 5).
• We are to overcome just as he overcame (chapter 6).
• After obtaining the victory, we will sit with him on his throne (the throne of His Father, the throne of the universe). And that moment is described in chapter 7.
