Mathew Chapter six....continues 5

19  “Do not lay up for yourselves treasures on earth, where moth and rust  destroy and where thieves break in and steal, 20  but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. 21 For where your treasure is, there your heart will be also.
 22  “The eye is the lamp of the body. So, if your eye is healthy, your whole body will be full of light, 23  but if your eye is bad, your whole body will be full of darkness. If then the light in you is darkness, how great is the darkness!
 24  “No one can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money.

Here in these verses three things are stated, the first one about laying up treasures, second about eye or vision and third about service.
 
The verse 19 is a complex sentence according to the English grammar. Means, in a complex sentence there will be a main clause and one or more subordinate clauses. The subordinate clauses qualify something that belongs to main clause. Here the subordinate clauses ‘where moth and rust destroy and where thieves break in and steal’ qualifies the 'earth' in the main clause ‘Do not lay up for yourselves treasures on earth’. What does it mean? On earth where moth and rust destroy and where thieves break in and steal means, on earth where physical changes and unrighteousness prevails there you should not lay up for yourselves. If there is any place on earth there physical changes do not occur and righteousness prevails there you can lay up treasures for yourselves. Otherwise you should not lay up for yourselves, but for others. Verse 20 says this same truth in the reverse order and the place where physical changes do not occur and righteousness prevails is named as heaven. And one important thing is the verse 21. If your treasure is there in unrighteous changing world, then your heart is also in that unrighteous changing world. If your treasure is in a righteous non-changing zone, your heart will also in righteous non-changing zone.

But this is the matter of a vision that specifies in verses 22 and 23. If your eye, your vision, is good, whole your body or whole your activities will be so, in light. Your all activities, whole body, are led by your vision. If your eye, your vision, is bad whole your activities will be in darkness or all the activities will be of darkness, a heart in unrighteous changing world. Those who have a good eye, vision, always will be in the righteous zone and serve there, God, other wise, in unrighteous region where money is the primary consideration. Any way nobody can give equal consideration for both. Either serves the money, unrighteous zone or the righteous zone, God. Those who serve money use God as a tool for making money and as their vision, eye, is perverted, they twist all divine principles to justify their activities and cheat genuine devotees.
