Matthew 6:22-24

Riverside(i) 22 "The lamp of the body is the eye. If your eye is clear your whole body will be lighted up, 23 but if your eye is bad your whole body will be darkened. If the light that is in you is darkness, how great the darkness is! 24 No one can serve two masters. For either he will hate one and love the other or he will hold to one and despise the other. You cannot serve God and Mammon.
