Jesus' Words / The Sound Eye
Matthew 6:22–23 · §65
22“The lamp of the body is the eye. If therefore your eye is sound, your whole body will be full of light. 23But if your eye is evil, your whole body will be full of darkness. If therefore the light that is in you is darkness, how great is the darkness!
22The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light. 23But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!
Thomas 24: His disciples said, "Show us the place where you are, because we need to look for it." He said to them, "Anyone who has ears to hear should hear! Light exists within a person of light, and they light up the whole world. If they don't shine, there's darkness." (a parallel saying preserved outside the four Gospels)
