Verse 20.— If a man say, I love God. How can any one say he loves the unseen One, and yet hates his brother, whom he sees and knows. Such a claim is mere pretense. The one so claiming, the apostle says, is a liar. Here, then, we need not be deceived. Should one claiming to be a teacher, claim that he loved God and hated his brother, that teacher is a deceiver, an antichrist; should he be a private person, he is simply a hypocrite. The brother we see, and know by our natural senses all his excellencies of character; he is God's image; him we hate. Now, how can it be said, while we hate him, we love the unseen God, whom we know only by the manifestations of himself that he has seen fit to give?
