Matthew 6:19-24 - The Sermon On The Mount: Treasure In Heaven
19 Lay not up for yourselves treasures upon the earth, where moth and rust corrupt, and thieves break through and steal: 20 but lay up for yourselves treasures in heaven, where moth and rust do not corrupt, and thieves do not break through and steal: 21 for where your treasure is, there will be your heart also.
22 For the light of the body is the eye. If thine eye may be clear, thy whole body will he lighted. 23 If thine eye may be bad, thy whole body will be dark. Then if the light which is in you is darkness, the darkness is so great.
24 No one is able to serve two masters: for he will hate the one, and love the other; or cleave to the one, and despise the other. You are not able to serve God and mammon.
