What does it mean that Christ 'is seated at the right hand of God'?
Answered in 1 source
This means Christ has completed his redemptive work and now reigns in authority and intercedes for believers.
Christ being seated at the right hand of God signifies the completion of his work of redemption and his exaltation in authority. As described in the sermon, after Christ's resurrection, he ascended and took his rightful place in heaven, indicating that all aspects of his work have been finalized. Hebrews 10:12 emphasizes this, stating, 'but this man, after he had offered one sacrifice for sins forever, sat down at the right hand of God.' His seated position denotes his ruling power and his role as our intercessor, assuring believers that their needs and requests are presented to the Father. Thus, Christ’s current reign encourages Christians, reminding them that he is actively involved in their lives and assures them of their salvation, as he continually advocates for them.
