Very truly, I tell you, anyone who hears my word and believes him who sent me has eternal life, and does not come under judgment, but has passed from death to life. “Very truly, I tell you, the 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. For just as the Father has life in himself, so he has granted the Son also to have life in himself; and he has given him authority to execute judgment, because he is the Son of Man. Do not be astonished at this; for the hour is coming when all who are in their graves will hear his voice and will come out—those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of condemnation. (John 5:24-29, NRSV)
He who believes has passed from death to life.
Not will pass, or might pass, or at some time in the future will pass. Has passed.
It has already happened.
Eternal life is not something we wait for. It is something we live in right now. Here and now.
If you hear the promises of Jesus and believe in God then you have eternal life now and death is no more.
You are living forever with Jesus
