Mt 6:19-23
Do not store up treasures for yourself here on earth, where moth and rust destroy it, and where thieves can steal it, Store up treasures for yourself with God, where no moth or rust can destroy it nor thief come and steal it. For where your treasures is, there also will your heart be.

The lamp of the body is the eyes; if your eyes sound, your eyes are diseased, your whole body will be full of darkness. If then the light in you is darkness, how great is that darkness!
