Jesus said that we should not consume ourselves with laying up treasures here on earth because they will inevitably be destroyed in one way or another. Instead, we should focus on investing in treasures in heaven that will last for eternity. The only way to invest in something eternal is to invest in other people. You do not get your reward when you die, you get your reward in the end because if you have been investing in others than you will continue to reap the rewards of those you’ve invested in investing in others and so on. Making disciples is the most important thing that we could do while here on earth.
