What does the Bible say about laying up treasures in heaven?

In Matthew 6:19-21, Jesus instructs us to not store up treasures on earth where they can decay or be stolen, but rather to invest in eternal treasures in heaven. The implication is that earthly possessions are temporary and unreliable, while spiritual investments yield eternal rewards. This passage emphasizes that our true priorities and affections are revealed by where we place our treasure. If our focus is on the things of this world, our hearts are not aligned with Christ, and we may find ourselves spiritually bankrupt in the end.
