John Wesley once said, "Suppose that a messenger of God, an angel, were now standing at your right hand. Would you not care to abstain from every word or action that you know would offend him? Yes, suppose one of your mortal fellow servants, a holy man, stood by you. Would you not be extremely anxious how you conducted yourself both in word and action? How much more cautious ought you to be when you know God Himself, the Holy One, is inspecting your heart, your tongue, your hand, your every movement!"
