Authority to Execute Judgment

“Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live. For as the Father hath life in Himself; so hath He given to the Son to have life in Himself; and hath given Him authority to execute judgment also, because He is the Son of Man.
Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear His voice, and shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
I can of Mine own self do nothing: as I hear, I judge: and My judgment is just; because I seek not Mine own will, but the will of the Father which hath sent Me.”
  John 5:25-30
