Short answer: Matthew 6:21 means your heart follows whatever you truly treasure. Jesus is teaching that what you invest in — your time, money, and attention — reveals and shapes what you love. Store up "treasure in heaven," and your heart will be drawn toward God rather than toward things that fade.
The context: treasure in heaven
Matthew 6:21 sits inside the Sermon on the Mount, in a passage on money and priorities (Matthew 6:19–24). Jesus contrasts two kinds of treasure: earthly treasure, which "moth and rust doth corrupt" and thieves steal (v. 19), and heavenly treasure, which lasts (v. 20). Verse 21 is the principle that ties it together, and it leads into His famous statement that "ye cannot serve God and mammon" (v. 24, KJV).
What it means, phrase by phrase
The King James Version reads: "For where your treasure is, there will your heart be also" (Matthew 6:21).
- "For" — This connects back to the command to store treasure in heaven. Verse 21 explains why that command matters.
- "where your treasure is" — "Treasure" is whatever you value and invest in most — not only money, but time, energy, and hope.
- "there will your heart be also" — Your affections follow your investments. Jesus reverses the assumption that we invest in what we already love; He teaches that we also come to love what we invest in.
This is a diagnostic verse. If you want to know what your heart truly values, look at where your resources actually go — your calendar and your spending often tell the truth more honestly than your intentions.

How to apply Matthew 6:21 today
Because the heart follows treasure, one of the most practical ways to grow in love for God is to invest in what He values — generosity, people, His kingdom. If your affections feel cold toward God, this verse suggests a surprising remedy: direct your resources toward Him and watch your heart follow. Reviewing where your money and time actually go is a spiritual exercise, not just a budgeting one. It gently exposes what you are truly treasuring and invites you to reinvest.
