Matthew 6:22-24

22“The eye is the lamp of the body. So if your eye is unclouded, your whole body will be full of light.

23But if your eye is evil, your whole body will be full of darkness. If the light in you is darkness, how dark it will be!

24“No one can serve two masters. He will hate the first master and love the second, or he will be devoted to the first and despise the second. You cannot serve God and wealth.
