Humans go to great lengths to build strongholds for their treasures, like Fort Knox, where a large portion of the USA's official gold reserves are stored. Imagine, all this trouble for so-called "treasures" that completely lose its value for you the day you die.
However, there is a treasure more precious than all the gold in Fort Knox. It is called Eternal Life. Through His Life, Death and Resurrection, Jesus Christ opened a deposit box for every human being in heaven. Every time you do a good deed to serve your fellow human, you make a deposit into that box.
Don't get tired of doing good things to your fellow humans. Hold on to the faith. Temporal life is short, but eternal life is, well... eternal!
