I wonder if things lost in this world could be regained later in heaven.

So that the things we know we have lost now--maybe we can hope that one day, and a not a day in this current life, we can hope to have it again.

In this world you just keep losing things. By God's grace He always blesses us with more and better things, but sometimes I wonder. I wonder especially to those things lost to sin... Is it possible to get it again in this life? Or is it gone now? Because of my own constant slavery to sin, are these certain gifts gone forever without a chance of getting it back in my life right now?

Would there be any point in having it in heaven?

Maybe it is gone forever.
