Since, then, you have been raised with Christ, set your hearts on things above, where Christ is, seated at the right hand of God. (Colossians 3:1 NIV)
He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power. After making purification for sins, he sat down at the right hand of the Majesty on high . . . (Hebrews 1:3 ESV; cf. Heb 8:1; 10:12; 12:2)
The one who conquers, I will grant him to sit with me on my throne, as I also conquered and sat down with my Father on his throne. (Revelation 3:21 ESV)
There Christ presently sits, ruling and reigning in ways that are relaxed, unhurried and irresistibly hopeful, along with all those he has purchased and made his own. His relaxed, hopeful presence permeates all who sit with him there, those redeemed souls bought with his love, the adopted and dearly loved sons and daughters of God.
As his peace rules their hearts, they are trained in his relaxed, hopeful ways of reigning. Participation with him in the living of their lives results in the fruits of his Kingdom presence and activity being made manifest in their day to day world – righteousness, peace and joy.
Those seated with him become like him in ways deeper than position or forensic declaration; they become united in intimate communion with him, becoming so deeply and pervasively identified with him that they end up discovering their true selves, hidden in him.
