Matthew 5: 14-16
Ye are the light of the world. A city that is set on an hill cannot be hid.
Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.
Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
Christ has given us the sacred responsibility to let our light - the Light of Christ within us - shine to others. We do that by striving to be like Him. When we serve others, we are serving our Father in heaven, and we glorify Him. It is our responsibility to help others, lift others when they are down, teach others, share goodness and the light we have within us with others.
We also have the responsibility to be humble enough to receive, because that is how we help others share their light.
