“Do not store up for yourselves [material] treasures on earth, where moth and rust destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where neither moth nor rust destroys, and where thieves do not break in and steal; for where your treasure is, there your heart [your wishes, your desires; that on which your life centers] will be also.
“The eye is the lamp of the body; so if your eye is clear [spiritually perceptive], your whole body will be full of light [benefiting from God’s precepts]. But if your eye is bad [spiritually blind], your whole body will be full of darkness [devoid of God’s precepts]. So if the [very] light inside you [your inner self, your heart, your conscience] is darkness, how great and terrible is that darkness!
