He may come back in yours, as well. However, he may not come back if you don't expect him to do so in your lifetime. Let me explain.
30 years ago a high school buddy visited me during my senior year in college. He told me with such intensity that he believed that Jesus was coming back soon and in his lifetime. I told him that I believed that Jesus was coming back but that it would be in the distant future. The look of disappointment because of my words affects me to this day.
Now this is the peculiar thing. As much as I've tried to locate this friend, it's as if he never existed although he's in my high school yearbook and there are people who remember him. He believed that Jesus was coming back soon and, I believe Jesus did come back soon.
This is how it happened. Quantum mechanics, as well as String/M Theory, postulate that there are an infinite amount of realities coexisting side by side. For those who believe that Jesus will come back some day in the distant future, they will continue living in a reality that is in agreement with their belief. For those who believe, as my friend did, that Jesus was coming soon, in that reality, Jesus did come soon. I am not talking about my friend dying.
Now this is the real conundrum. Even though my friend has experienced Christ's second coming in his reality, in my reality, I'm still waiting for Jesus' Second Coming. Additionally, my friend my well exist somewhere in this same reality I live in, but completely oblivious of my existence or I of his. Yes, in each of these infinite variations--or parallel universes--each of us has an identical twin, with slight variations depending on the choices we made in those distinct realities.
This can account for the seemingly mysterious disappearances of people that should continue to exist in my reality, but that have apparently disappeared.
Now more than ever, believing that Jesus is coming soon is crucial. Only those that really believe and internalize that belief will diverge from this reality in which Jesus delays into another reality where he, in fact, will come soon.
Since the word of God is one, all the different realities or parallel universes share the same Sacred text. This is as good an explanation, as any, as to why the New Testament states over and over again that Jesus is coming soon. He comes soon to those who want him to. To those who don't want him to come soon, he simply does not.
I am not talking about a secret rapture. Christ comes back only once within each separate reality.
Envision Christ returning soon and in your lifetime. Hope and wait for it with something greater than faith. Hope for it with absolute certainty not just a half-hearted wish. Pray without ceasing that Christ returns in your lifetime. He will return soon if you want it badly enough.
