The duty of Christians toward their fellow men and women is to let their light shine, not to force on them their interpretations of God’s designs.
If those who set themselves to explain the various theories of Christianity had set themselves instead to do the will of the Master, the one object for which the gospel was preached, how different would the world now be!…
Unhindered by Christians’ explanations of Christianity, undeterred by having their acceptance forced on them, but attracted instead by their behavior, men would be saying to each other, as Moses said to himself when he saw the bush that burned but was not consumed, “I will now turn aside to see this great sight!” All over the world, people would be drawing near to behold how these Christians loved one another and how just and fair they were to every one that came into contact with them. They would note that the goods Christians had to sell were the best, their weights and measures most dependable, their prices most reasonable, their word most certain, their smiles most genuine, their love most selfless!… They would see, in short, a people who lived by their principles of belief, not merely talked and disputed about them.
