I hope I approach this delicately since I know this is common language used to describe the relationship Christians have with Jesus Christ. To be honest, I don’t know how this terminology originated but I believe it is a more recent phenomenon.

After the resurrection, he ascended into heaven where he sits at the right hand of the Father (Acts 2:33; Hebrews 1:3; 8:1; 12:2).
