What do you think about this possibility?

Jesus did that very thing. He overcame death and now we have nothing to fear.

Delusion.

Since you have asked, my thought about it is this .....

Based on all of Jesus’ long-aborted promises,
his being unable to do anything that was required of a messiah,
and his now legendary inability to return, we can now rightfully assume that each and
every one of the past two thousand years in a row can tell us, that God does not need Christians … or their “christ”.

It is obvious that the trail to your ‘Jesus’ does not exist beyond your own thinking that it does.

“He will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore.”—Revelation 21:4
“The lame will leap like the deer.”—Isaiah 35:6
“The eyes of the blind will be opened.”—Isaiah 35:5
“All those in the memorial tombs will . . . come out.”—John 5:28, 29
“No resident will say: ‘I am sick.’”—Isaiah 33:24
“There will be an abundance of grain on the earth.”—Psalm 72:16

That is what the Bible says. When God's Kingdom wipes out all the human governments now ruling, Jesus will be king over the entire earth, along with his 144,000 co-rulers (king priests) who have "been bought from the earth" to be with him in heaven. (Daniel 2:44; John 18:36 Revelation 1:5+6, Revelation 5:9+10, and Revelation 14:1-3) On a small scale, Jesus proved that he could awaken people from the sleep of death. Yes, the Bible likens death to sleep. (John 11:11; Psalms 13:3; Matthew 9:24; Acts 7:60; 1Corinthians 15:6) John 5:28+29 tells us: "Do not be amazed at this, for the hour is coming in which all those in the memorial tombs will hear his voice and come out, those who did good things to a resurrection of life, and those who practiced vile things to a resurrection of judgment." Yes, all who are resurrected from the sleep of death will have been given another chance to live their lives according to Jehovah's standards and will be "worshiping with spirit and truth" as Jesus told the Samaritan woman at John 4:23+24. What a wonderful hope Jesus ransom sacrifice holds out to those "exercising faith in him." (John 3:16) I invite you to learn more Bible teachings from the international website, jw.org.

One thing you have missed is how the Bible defines death.

The last enemy, death, will be swallowed up for ever (Isaiah 25:8) is a promise that God has made and a promise that all Christians have confidence in. That is because Christ Jesus was resurrected from the death and he is the firstfruits of all who shall be resurrected.

1 Corinthians 15:54: "When the perishable has been clothed with the imperishable, and the moral with immortality, then the saying that is written will come true: "Death has been swallowed up in victory."

2 Corinthians 5:4-5 describes how the mortal body will "be clothed with our heavenly dwelling, so that what is mortal may be swallowed up by life. Now it is God who has made us for this very purpose and has given us the Spirit as a deposit, guaranteeing what is to come."

2 Corinthians 5 goes on to describe how those who belong to Christ long to be with him and verse 10 reminds us that "we must all appear before the judgment seat of Christ, that each one may receive what is due to him for the things done while in the body, whether good or bad."

Make no mistake. It is only through the life, death and resurrection of Christ Jesus that believers can have confidence in the resurrection to come, when death will be swallowed up for ever. God offers this free pardon to all who repent and who turn in saving faith to what God, in Jesus, has already done to atone for the sins of the world.

But not all will accept this undeserved gift and will have to account for their actions before God on the Day of Judgment. Unless we have entered into the new covenant and Christ Jesus is our advocate, we will die in our sins. Christ Jesus has alread done what is necessary to redeem us, if we but turn to him in faith and repentance. Then we, too, will be the beneficiaries of that wonderful promise of eternal life!

It's nothing more than a silly fantasy since god doesn't exist.

I'm in line, but they haven't called my number yet.
