Matthew 6:19-22

Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal: but lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: for where your treasure is, there will your heart be also. The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.
Matthew 6:19-22
