Deuteronomy 13:4 NIV 

[4] It is the Lord your God you must follow, and him you must revere.  

Keep his commands and obey him; serve him and hold fast to him.  

Malachi 3:10

Bring all the tithes into the storehouse,

that there may be food in My house, and try Me now in this,"

Says the Lord of hosts,

If I will not open for you the windows of heaven

And pour out for you such blessing

That there will not be room enough to receive it.

Matthew 5: 14-16 

You are the light of the world. A city that is set on a hill cannot be hidden. Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house.

Let your light so shine before men, that they may see your good works and glorify your Father in heaven.
