In 1 Peter 1:4 at the end of the verse it says “reserved in heaven for you.”
For those that have not read it Peter is referring to our live eternal that we were promised through Christ sacrifice for us upon the cross.
In particular I want to draw your attention to the word “reserved” of the King James Version of this verse. The actually meaning of the word in the Greek is to hold, preserve, and watch. Many have this image though not studying the Bible themselves that Heaven is all there is beyond this life we now live, but that is not what is promised us. Look at the first part of the verse: “To an inheritance incorruptible, and undefiled, and that fadeth not away” The main thing I wish you to note is the statement “that fadeth not away.” It will last forever, but its time is not yet revealed to any and they are held over in Heaven until such time as God finishes what He is going to do with those upon this planet.
We know that we shall be in clean of our sins. We know we will live forever. Yet people even within Christendom go about as if this life, this short life is all that we are promised. Yet that is not what the Bible teaches. If people would truly read the Bible then they would learn what is true and what is real. All I can do is encourage them to do so, but it is up to them to do it.
