“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.”
John 5:25 — Greek Interlinear
Church Fathers on John 5:25
Some one might ask you, The Father quickens him who believes in Him; but what of you? do you not quicken? Observe you that the Son also quickens whom He will; Verily, verily, I say to 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.
After, The hour comes, He adds, and now is; to let us know that it will not be long before it comes. For as in the future resurrection we shall be roused by hearing His voice speaking to us, so is it now.
Here He speaks with a reference to those whom He was about to raise from the dead: viz. the daughter of the ruler of the synagogue, the son of the widow, and Lazarus.
