Two masters

一个人不能事奉两个主。不是恶这个爱那个，就是重这个轻那个。你们不能又事奉神，又事奉玛门。（玛门是财利的意思）

Men can not serve 2 masters. You either hate this one or love the other one. You can emphasis on this one or lessening on the other one. You can not serve both God and the Money.

The rasional is:
God is the real master of our lives.
Money is only the medium or something to be used for serving. We serve our Lord by not enslaving to our money that works for the Lord are not for money.Jesus was betrayed by Judas with an offer of 30 pieces of silver  coins according to an account in the Gospel of Matthew 26:15 in the New Testament.

So they decided to use the money to buy the potter's field as a burial place for foreigner. (Matthew 27:7)
In the New Living Translation stated
After some discussion they finally decided to buy the potter’s field, and they made it into a cemetery for foreigner.
Noticed that if it was not because of the thirty silver coins would Judas betray Jesus? If it was not because of the money would the foriegner find a place to burry?

 King James Version of the Bible the text reads: For where your treasure is, there will your heart be also. The World English Bible translates the passage as: for where your treasure is, there your heart will Matthew (6:21)

Therefore the main differetiation of the Money and the Master is on their priority in our lives. We must put our Lord first as the master that we are serving. The word stated whatever we done for the least amongst us be considered as done to our Lord. Therefore, we must ready  to serve not to be served. We serve our master.
