Hello sir, I want to know about what happens to our whole life’s stored memory after death?
I am assuming you want a biblical answer to this question, not a scientific answer or my opinion. The Bible is not explicit about what happens to our memories when we are in heaven (or in hell, for that matter). There is a passage in Isaiah which suggests an answer. In Isaiah 65:17 God tells his people, “Behold, I will create new heavens and a new earth. The former things will not be remembered, nor will they come to mind.”
Here is how I interpret this passage (of course, you should decide for yourself how you will understand the meaning). I do not believe that we literally will be completely unable to remember the past when we are in heaven. The second phrase seems appropriate: “nor will they come to mind.” To me it is like the thoughts we had when we were small children. We can remember them vaguely and value them, but as adults we realize these were childish thoughts and bear this in mind. We have moved on to greater things. I believe when we are in heaven, it will be so amazing that the things of the past, though not literally forgotten, will fade into relative insignificance, so that they will not “come to mind.”
Remember that I already said the Bible is not explicit and this is my understanding, not some sort of iron-clad biblical proof. I suggest you look at biblical passages on the afterlife and reach your own conclusion.
