Matthew 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 your heart will be. The lamp of the body is the eye; if your eyes are sound, your whole body will be in the light. If your eyes are diseased, your whole body will be in darkness. Then, if your light has become darkness, how dark will be the darkest part of you!
