Your eye is a lamp for your body. A pure eye lets sunshine into your soul. But an evil eye shuts out the light and plunges you into darkness.

Luke 11:34

My prayer is not for the world, but for those you have given me, because they belong to you....

Make them pure and holy by teaching them your words of truth.

John 17:9,17

God blesses those whose hearts are pure, for they will see God.

Matthew 5:8
