For where your treasure is, there will your heart be also.
All Commentaries on Matthew 6:21 Go To Matthew 6
Theophylact of Ochrid
AD 1107
. Having first cast out the sickness of vainglory by what He said before, now He speaks about non-possessiveness. For men possess more than they need because of vainglory. He shows how unprofitable earthly treasure is: moth and corruption consume food and clothing, and thieves steal gold and silver. And then, so that no one should say to Him that not all treasure is stolen, Jesus says, even if nothing is lost in this manner, are you not wretched for being nailed down by your worries over wealth? This is why He says, "Where your treasure is, there will your heart be also."
