  What can be understood from  Christ's  sitting at  the right hand of the Father?
 The Father has no right and has  no left  because He is Infinite and He fills all things. There is no  vacuum at  His right side for another to sit there. So what is the meaning of  sitting at His right side? The word 'right' is  a symbol of power and of  righteousness and of majesty. This symbolism is  similar to the Lord's  expressions 'your right eye' and 'your  right hand' in (Matt. 5:29,30),  The  right hand of the Father means the power of the Father,  the  righteousness of the Father and the majesty of the Father. That is  why  it was once said that the Son sat at the right hand of the Power and  at  another that He sat at the right hand of the Majesty. The word 'sat'  here  means remained.
 This means that the Son who, in emptying Himself,  appeared weak in  front of you; was slapped on the face, scourged and  crucified, by His  ascension entered into His power and you will not see  Him any more in  weakness. And at His Second Coming, He will come on  the clouds in His  glory, surrounded by all the holy angels (Matt.  25:31), because at His  Second Coming He will come with power and great  glory (Matt. 24:30).
 Also, the Son who stood in front of you as a sinner  and criminal, and  who stood before the Father carrying all the sins of  the world, will sit  at the right hand of His Father, that is, in His  righteousness, and  nobody can dare condemn Him any more.
 The expression  "sitting at the right hand of the Power" means   that the stage of emptying Himself has ended and that the Son entered   into His glory. That is why it is said that at His Second Coming, He  will come,, in His own glory, and His Father's (Lk. 9:26), and it is  also said: "For the Son of Man will come in the glory of His Father with His angels"  (Matt. 16:27). This glory is the  sitting at the right hand of the Father
