What does it mean that Christ sat down at the right hand of God?

The act of Christ sitting at the right hand of God, as mentioned in Hebrews 10:12, symbolizes that His work of redemption is complete. He offered His one perfect sacrifice and then sat down, which indicates that nothing more is needed for salvation. In Reformed theology, this speaks to Christ's authority and His reign over creation. It assures believers of His presence and intercession for them. As their High Priest, He stands as their advocate, mediating their petitions before the Father. Thus, His session at the right hand is a testament to His victory over sin, death, and the powers of darkness.
