Matthew 5:16 "In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven"
Hebrews 1:3 "Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;"

As christians we ought to do everything for the Glory of God..
Also God want us to Carry his Name every where we go! So that all Glory will belong to him!
