25 Truly, truly, I say to you, an hour is coming, and is now here, when the dead will hear the voice of the Son of God, and those who hear will live.
Paul tells us in the book of Ephesians that we are all born dead in our trespasses and sins. This is a spiritual death. It is the death that God spoke of to Adam when he said that anyone who eats of the forbidden fruit would surly die. When Adam ate of that fruit he did not die physically immediately (this came later), but he did die spiritually, which has been passed down to all humanity. It is a condition we are all born into – death. This deadness creates within us a deafness – we are unable to hear the voice of Christ which is required for us to have life. So how can we hear? Later in John’s Gospel Jesus will say, “My sheep hear my voice.” Therefore, those who are God’s sheep will hear his voice and they will live. But not because they decided of themselves, but because Christ gave them life according to his will (v.21). These are words of assurance and comfort for us, because if we treasure Christ, turned from our sins and to the living and true God, then we who were dead have been made alive because we heard the voice of our Savior call our name and give us life.
