Matthew 6:19-24 - The Sermon On The Mount: Treasure In Heaven
19 Lay not up for yourselves treasures upon earth, where the rust and canker spoil, and where thieves dig through and steal: 20 but lay up for yourselves treasures in heaven, where neither rust nor canker spoil, and where thieves do not dig through and steal; 21 for where your treasure is, there will your heart be also.
22 The lamp of the body is the eye: if therefore thine eye be transparent, thy whole body shall be enlightened. 23 But if thine eye be vitiated, thy whole body will be darkened. If therefore the light which is in thee be darkness, how great is that darkness!
24 No man can serve two masters: for he will either hate the one, and love the other; or he will adhere to the one, and disregard the other. Ye cannot serve God and mammon.
