Matthew 6:22
The eye is the lamp of the body. If your eyes are good, your whole body will be full of light.
What it says
The eye functions as the lamp that fills the body with light when it is good.
What it is doing
It links sight with the body’s inward condition.
In context
22The eye is the lamp of the body. If your eyes are good, your whole body will be full of light. 23But if your eyes are bad, your whole body will be full of darkness. If then the light within you is darkness, how great is that darkness! 24No one can serve two masters: Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and money.
