Matthew 6:19-24

19Lay not up for yourselves treasures upon the earth, where moth and rust spoils, and where thieves dig through and steal;

20but lay up for yourselves treasures in heaven, where neither moth nor rust spoils, and where thieves do not dig through nor steal;

21for where thy treasure is, there will be also thy heart.

22The lamp of the body is the eye; if therefore thine eye be single, thy whole body will be light:

23but if thine eye be wicked, thy whole body will be dark. If therefore the light that is in thee be darkness, how great the darkness!

24No one can serve two masters; for either he will hate the one and will love the other, or he will hold to the one and despise the other. Ye cannot serve 1God and mammon.
