perspective on eternity

lets just assume there is a person you have not seen for a decade. and there is barely a chance you will see each other in a life time because of current circumstances. what hope do you have at all in case you are really longing to see that person and vice versa? none if you have no perspective on eternity at all. what do i mean by that ? you only can have a true belief or even knowledge of eternity if you are saved by the blood of Jesus Christ. If you both believe that you will take BOTH part in an eternal life and all the unrealized longings for each other will be redeemed under the blessings of the almighty God. This all will sound strange, crazy, nonsense to the unbeliever. i call this knowing, conscious hope for eternal communion.
