Matthew 5:16 (ESV) 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.
I remember hearing of two men who had charge of a revolving light in a lighthouse on a storm-bound and rocky coast. Somehow the machinery went wrongs and the light did not revolve. They were so afraid that those at sea should mistake it for some other light, that they worked all the night through to keep the light moving round. Let us keep our light in the proper place, so that the world may see that the religion of Christ is not a sham, but a reality. D. L. Moody (Anecdotes, Incidents and Illustrations)
