For where your treasure is, there will your heart be also. No one can serve two masters; for either he will hate the one and love the other, or he will stand by and be devoted to the one and despise and be against the other. You cannot serve God and mammon (deceitful riches, money, possessions, or whatever is trusted in).
(Matthew 6:21,24)

The reason why people dont like to talk about money is becauae it will tell on them.

All we have to do is look at how you manage or spend money and we will trruly see where your heart is.

Where is your treasure?  Where do you put it?  

In the things of this world?  Or in the things of God, in his ministries?
