Not only in this case, but all through his Epistles, John continues to unravel the tangled web of hypocrisy. Ah, that deceit should steal such gentle shapes and seem like Truth! To show the diverging point between facts and sayings, between realities and professions, between those who have, and those who only say that they have, was his constant aim. It may interest you just to open your Bibles and turn to one or two of the passages that illustrate this. In his first chapter, at the sixth verse, he has been speaking of those who walk in the light and have fellowship with God, and he adds, "If we say that we have fellowship with Him, and walk in darkness, we lie, and do not the truth." Then in the text he speaks of those who know Christ, and he adds, "He that says, I know Him, and keeps not His commandments, is a liar, and the Truth is not in him." And further on, in the ninth verse, speaking of those who have the light, he says, "He that says he is in the light, and hates his brother, is in darkness even until now." Not to multiply the instances, there is a notable one in the fourth chapter, at the twentieth verse, "If a man says I love God, and hates his brother, he is a liar: for he that loves not his brother whom he has seen, how can he love God Whom he has not seen?" So to have a thing, or to boast that you have it—to be, or to pretend to be such-and-such a character—are as opposite as white and black, as light and darkness.
