20 If someone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen, how can he love God whom he has not seen? 21 And this commandment we have from Him: that he who loves God must love his brother also. (1 John 4:20–21)
There is an inseparable link between loving God and loving fellow Christians. (The “brother” in this passage is one’s fellow Christian, a fellow child of God.) We cannot love God while hating a brother. Hatred is a dark, sinister, and deceptive sin. It can masquerade as self-vindication when we have been slighted (or, think we have been slighted) by another. Left uncorrected, hated festers, convincing us we are truth-tellers when we say we love God. But, in fact, we are liars. As you concentrate on loving God “with all your heart, with all your soul, and with all your mind,” be careful not to sabotage your effort by holding animosity in your heart against your brother. Remembering the Golden Rule helps: “Therefore, whatever you want men to do to you, do also to them, for this is the Law and the Prophets” (Matthew 7:12).
