Is it really good-bye, when someone passes from this life? Or is it, see you later?
Beliefs are as varied and different as the individual. According to what they have been taught, what they have come to believe in and on their own, it could be either. There are those who believe that once you die, that’s it. You are over, you return to the dust of the earth and you are no more. To me, that seems sad and a great loss. I would imagine that for those who believe in that manner, for them it is a closure. Dead and done so to speak. One doesn’t have to concern themselves with any form of eternity.
Some believe in reincarnation. You live a life, you die, then you come back. An eternal loop of trying to get it right. Or is it? A quick check of Wikipedia has given me this information should you be interested: https://en.wikipedia.org/wiki/Reincarnation
Here is what the Bible says about reincarnation: https://bible.org/question/what-does-bible-say-about-reincarnation
There are those who believe in an eternal afterlife. Some believe only in the good and some believe there is a good and a punishment side.Here is what is found in the Bible about an afterlife: https://www.openbible.info/topics/afterlife
There are those who believe that the ones who have gone on before can and do drop by for visits. Personally I don’t believe that is possible, but what I do believe is that angels can delivery messages from them.https://www.trusting-in-jesus.com/Angels.html In the Bible in Luke chapter 16 verse 26 Abraham is telling the rich man who has died; 26 And besides all this, between us and you a great chasm has been set in place, so that those who want to go from here to you cannot, nor can anyone cross over from there to us.’ (NIV version)
Was it good-bye?
When Jesus was crucified and placed in a tomb, many thought, that was all there was. Jesus had said, “It is finished” so everything they had thought was coming, was not. And yet, on that third day, He was resurrected. For forty days he was seen by many, proving He was alive. After which He ascended to Heaven to await the time of His return.

As a Christian, I believe that this life, is but a journey, a temporary place that will pass away. As a Christian, I believe there is a new life of eternity waiting. Once I arrive, all who have gone on before who believed, will be there waiting for me. So no, for those who leave before me, it isn’t good-bye.
It is, see you later.

I believe this, to a point. I believe we sleep until Christ’s Return when he raises us all from the dead and takes us with him to Heaven.
The way I see it, whether we go directly to be with Him, or sleep for a while first, the important thing, is the believing, the faith, the knowledge of our name in the Book of Life and that we will end up there with Him someday.
I love your last paragraph, Rebecca, perfect. 🙏🏻✝️
Thank you John.
I’ve had too many experiences with the other side to believe otherwise. It’s definitely “see you soon” if you want to get technical hehe. 🙂
Yes, “see you soon” is better.
